Other forms: carabiners
A carabiner is the sprung metal loop that clips a rope to a harness. Clip in the carabiner, a locking carabiner, the carabiner failed.
The locking kind has a screwgate and is used anywhere a failure would be fatal. The name is short for a German word meaning carbine hook, since soldiers used them to sling a weapon long before climbers took them up.
