Often referred to as carabiner-style or as mini-biners, carabiner keyrings and other light-use clips of similar style and design have also become popular. Most are stamped with a “Not For Climbing” or similar warning due to a common lack of load-testing and safety standards in manufacturing. While from an etymological perspective any metal attaching link with a spring gate is technically a carabiner, the strict usage among the climbing community specifically refers"
"Sling (climbing equipment) A sling or runner is an item of climbing equipment consisting of a tied or sewn loop of webbing. These can be wrapped around sections of rock, hitched to other pieces of equipment, or tied directly to a tensioned line using a Prusik style knot. They may be used as anchors, to extend an anchor to reduce rope drag, in anchor equalization, or to climb a rope. Slings come both sewn to length and assembled from loose webbing knotted as desired. Common sewn lengths include , , , and . They are available in widths of ."

"Circlip A circlip (a portmanteau of ""circle"" and ""clip""), also known as a C-clip, Seeger ring, snap ring or Jesus clip, is a type of fastener or retaining ring consisting of a semi-flexible metal ring with open ends which can be snapped into place, into a machined groove on a dowel pin or other part to permit rotation but to prevent lateral movement. There are two basic types: internal and external, referring to whether they are fitted into a bore or over a shaft. Circlips are often used to secure pinned connections. When used to retain piston wrist pins or"
"Prusik A Prusik ( ) is a friction hitch or knot used to attach a loop of cord around a rope, applied in climbing, canyoneering, mountaineering, caving, rope rescue, ziplining, bondage, and by arborists. The term Prusik is a name for both the loops of cord and the hitch, and the verb is ""to prusik"". More casually, the term is used for any friction hitch or device that can grab a rope (see autoblock). The word is often misspelled as Prussik, Prussick or Prussic, as it is a homophone with the term prussic acid. The Prusik hitch is named after"
"Climbing harness A climbing harness is an item of climbing equipment for rock-climbing, abseiling, or other activities requiring the use of ropes to provide access or safety such as industrial rope access, working at heights, etc. A harness secures a person to a rope or an anchor point. In its simplest form, a harness can be made from a length of rope or a nylon webbing tied round the waist. However this is extremely uncomfortable unless the wearer is very light. It can also ride up to the abdomen or even the diaphragm under load and cause serious injury. Looping"

Hikers and outdoor sports enthusiasts sometimes use ""survival bracelets"" made of several feet of paracord which is woven into a compact and wearable form. Such bracelets are meant to be unraveled when one needs rope for whatever purpose — securing cargo, lashing together poles, fixing broken straps or belts, or assisting with water rescues. Young survivalists (Girl Scouts and Boy scouts) are also taught the importance of using the paracord as a survival tool. On the other hand, the paracord is a poor choice for an emergency tourniquet as its small diameter"

R-clips are commonly used to secure the ends of round shafts such as axles and clevis pins. The straight leg of the R-clip is pushed into a hole near one end of the shaft until the semicircular ""belly"" in the middle of the other, bent leg of the R-clip grips one side of the shaft resisting any force removing"

The method is also useful for much smaller items such as for keeping earphone cables from tangling. Depending on the thickness and length, one can use palms of hands stretched out to the sides (crossing over the neck), two knees, passive side palm and elbow, or two fingers of the passive hand. The following is for the extra long climbing rope. Start with both rope ends in one"

Overall there is a huge variety of climbing ropes available for different purposes; for instance, there are well over one hundred different dynamic single ropes (the most popular rope system in climbing). Kernmantle ropes are still used in sailing and other sports, but the technical requirements are usually not as rigorous for such purposes as for climbing, since those applications are not as critical to safety. Small kernmantle ropes are commonly called accessory cords; they are often used to make prusik knots and loops"
"Crocodile clip A crocodile clip / croc clip (also alligator clip) is a sprung metal clip with long, serrated jaws which is used for creating a temporary electrical connection. This simple mechanical device gets its name from the resemblance of its jaws to that of an alligator's or crocodile's. It is used to connect an electrical cable to a battery or some other component. Functioning much like a spring-loaded clothespin, the clip's tapered, serrated jaws are forced together by a spring to grip an object. When manufactured for electronics testing and evaluation, one jaw of the clip is typically permanently"
"Stirrup A stirrup is a light frame or ring that holds the foot of a rider, attached to the saddle by a strap, often called a stirrup leather. Stirrups are usually paired and are used to aid in mounting and as a support while using a riding animal (usually a horse or other equine, such as a mule). They greatly increase the rider's ability to stay in the saddle and control the mount, increasing the animal's usefulness to humans in areas such as communication, transportation and warfare. In antiquity, the earliest foot supports consisted of riders placing their feet under"
"gudgeon pins, the clips are known as wrist pin clips, wrist pin retainers, or gudgeon pin clips. The most commonly used circlip for this application is a simple spring steel circlip, or plain wire ring. Common examples include e-clips (e-ring) and the (both internal and external) snap ring or circlip. These general types of fasteners are sized to provide an interference fit onto (or into, in the case of an internal fastener) a groove or land when in use, such that they must be elastically deformed in order to install or remove them. The term ""Jesus clip"" comes from the"
"The name ""harness loop"" derives from the fact that the knot was used when assisting horses on difficult terrain. Similarly, the name ""artillery loop"" or ""artilleryman's hitch"" derives from the fact that it was used when hauling field artillery into position. Artillery loop The artillery loop (also harness loop or manharness hitch) is a knot with a loop on the bight for non-critical purposes. The artillery loop must have the loop loaded or it will slip and contract easily. It is an inferior knot to the alpine butterfly knot, possibly dangerously so, in that it can be yanked out of"
"Fixed rope In mountaineering, a fixed rope or fixed line is the practice of fixing in place bolted ropes to assist climbers and walkers in exposed mountain locations. They are used widely on American and European climbing routes, where they may be called via ferrata routes, but are not used in ""Alpine style"" mountaineering. Many guided expeditions to any of the eight-thousanders normally set up fixed rope on steep or icy sections of the route. For example, on the Hillary Step of Mount Everest, fixed rope was used to reduce the bottleneck of climbers that typically results from climbing this"

The first climber who used a carabiner for climbing was German climber Otto Herzog. The Maillon (or Maillon Rapide) performs a similar function to a carabiner but instead of a hinge has an internally threaded sleeve engaging with threads on each end of the link, and is available in various shapes and sizes. They are very strong but more difficult to open, either deliberately or accidentally, so are used for links which do not need to be released"

A radium release hitch is typically tied with 10 meters of 8mm rope and"
"Butterfly loop The butterfly loop, also known as lineman's loop, butterfly knot, alpine butterfly knot and lineman's rider, is a knot used to form a fixed loop in the middle of a rope. Tied in the bight, it can be made in a rope without access to either of the ends; this is a distinct advantage when working with long climbing ropes. The butterfly loop is an excellent mid-line rigging knot; it handles multi-directional loading well and has a symmetrical shape that makes it easy to inspect. In a climbing context it is also useful for traverse lines, some anchors,"

A daisy chain is a strap, several feet long and typically constructed from one-inch tubular nylon webbing of the same type used in lengthening straps between anchor-points and the main rope. The webbing is bar tacked at roughly two-inch intervals (or, in the past, tied) to create a length of small loops for attachment. Unlike the use of similar devices in backpacking, daisy chains in technical rock climbing are expected to"
"spring-loaded camming devices, nuts and chocks, and slings, for hitching natural features. Contemporary alternatives to pitons, which used to be called ""clean climbing gear"", have made most routes safer and easier to protect, and have greatly contributed to a remarkable increase in the standards of difficulty notable since about 1970. Pitons are now regarded as highly specialized equipment, needed by a small minority of climbers interested in routes of peculiar difficulty. Even clean gear can damage rock, if the rock is very soft or if the hardware is impacted with substantial force. A falling climber's energy can drive a camming"

Diamond hitch The diamond hitch is a lashing technique used mainly in the field of equine packing, to secure a set of objects, for instance a pair of pack-bags, pack-boxes or other gear onto a base, for instance a pack saddle frame, in which case it requires the use of a lash cinch. In the general sense it requires the base to be equipped with at least two points of anchorage, and a rope which is used to lash the object down onto the base. There are two types of Diamond Hitches,"

"traditional climbing, the protection generally is removable. However, many significant first ascents in the U.S. done with a combination of crack gear and bolts placed on lead were termed ""traditional"" at the time (see below discussion). Usually nuts or spring-loaded camming devices (often referred to as ""cams"" or ""friends"") are set in cracks in the rock (although pitons are sometimes used). In sport climbing the protection is metal loops called hangers. Hangers are secured to the rock with either expanding masonry bolts taken from the construction industry, or by placing glue-in bolt systems. In ice climbing the protection is made-up"

"Pitch (ascent/descent) In rock climbing and ice climbing, a pitch is a steep section of a route that requires a rope between two belays, as part of a climbing system. Standard climbing ropes are between 50 and 80 metres long, so a pitch is always shorter, between two convenient ledges if possible; longer routes are multi-pitch, requiring the re-use of the rope each time. In free climbing, pitch refers to classification by climbers of the difficulty of ascent on certain climbing routes. In advanced climbing or mountaineering, another definition of ""pitch"" is not restricted by the length of the rope."
"Maillon A maillon, maillon rapide or quick link is a metal link, similar to a carabiner. Maillons have a threaded sleeve which tightens over a thread, as opposed to a hinged gate like a carabiner, making them stronger, but more difficult to use. Like carabiners, maillons are available in a range of shapes and thicknesses (i.e., strengths), and often offer greater versatility over carabiners as their different shapes and lack of hinged gates allow them to be used in multi-directional load situations. The word ""maillon"" comes from the French language, meaning ""link"". Maillons are used primarily in climbing and caving."

"Munter hitch The Munter hitch, also known as the Italian hitch or the Crossing Hitch, is a simple knot, commonly used by climbers, cavers, and rescuers as part of a life-lining or belay system. To climbers, this knot is also known as HMS, the abbreviation for the German term ""Halbmastwurfsicherung"", meaning ""half clove hitch belay"". This technique can be used with a special ""pear-shaped"" HMS locking carabiner, or any locking carabiner wide enough to take two turns of the rope. The Munter hitch is named after a Swiss mountain guide, Werner Munter, who popularised its use in mountaineering around 1970."

"Hex (climbing) A hex is an item of rock climbing equipment used to protect climbers from falls. They are intended to be wedged into a crack or other opening in the rock, and do not require a hammer to place. They were developed as an alternative to pitons, which are hammered into cracks and are more prone to damage the rock. Most commonly, a carabiner will be used to join the hex to the climbing rope by means of a loop of webbing, cord or a cable which is part of the hex. Hexes are a type of nut, a"
