0 an object used for attaching two things, for example by a climber for attaching a rope to a belt. It is oval or like a letter D in shape, with a part that opens and closes:
I unclipped my carabiner from the rope.
Rock climbers frequently connect two non-locking carabiners with a short length of nylon web to create a quickdraw.
Novelty carabiners are also commonly used as keyrings for ease of access and exchange.
Pitons and carabiners were just starting to be effectively adapted for use in the mountains.
A quickdraw consists of two non-locking carabiners connected together by a short, pre-sewn loop of webbing.
Most practitioners run the climbing rope through two screwgate carabiners attached to the anchor, to provide backup in case one becomes undone.
Ropes are usually rigged using bolts, slings, and carabiners.
Locking carabiners offer a method of preventing the gate from opening when in use.
Most importantly, the carabiner must be of round cross section for friction.
