Carabiner

Shackle with a spring-loaded gate / From Wikipedia, the free encyclopedia

Dear Wikiwand AI, let's keep it short, summarize this topic like I'm... Ten years old or a College student

A carabiner or karabiner (/ˌkærəˈbnər/)[1] is a specialized type of shackle, a metal loop with a spring-loaded gate[2] used to quickly and reversibly connect components, most notably in safety-critical systems. The word is a shortened form of Karabinerhaken (or also short Karabiner), a German phrase for a "spring hook"[3] used by a carbine rifleman, or carabinier, to attach his carabin to a belt or bandolier.
