A carabiner comprises a body 10 having a free end and a pivot end between which is defined an opening. A gate 24 is carried on the body 10 close to the pivot end, the gate 24 being pivotable between a closed position, in which it closes the opening, and an open position. A locking mechanism is carried on the gate which, in a locked condition, prevents movement of the gate from the closed position. In an unlocked condition, the locking mechanism allows movement of the gate 24 to its open position. The locking mechanism includes a sleeve 40 that can be manipulated by a user to place the locking mechanism in the unlocked condition. In order to place the locking mechanism in the unlocked condition, the sleeve 40 must be subject sequentially to an initial rotation about the gate 24, translation along the gate 24, and further rotation about the gate 24. |
