A carabiner or karabiner is a specialized type of shackle, a metal loop with a spring-loaded gate used to quickly and reversibly connect components, most notably in safety-critical systems. The word is a German phrase for a "spring hook" used by a carbine rifleman, or carabinier, to attach items to a belt or bandolier.
The carabiner has been improved several times over the decades, making it more lightweight, reliable and durable.
