Abstract: A carabiner having a bow, which has an insertion opening and first and second ends that bound the insertion opening, a closing part, which assumes a closed position in the closed state of the carabiner, in which it closes the insertion opening, first and second ends of the closing part engage with the first and second ends of the bow, and the closing part can be pivoted relative to the bow about a pivot axis formed at the engaging first ends of the bow and the closing part into a first open position in order to open the carabiner, and an actuating arm, which retains the closing part in the closed position in an initial position and is movable in order to open the carabiner. The closing part can be further pivoted relative to the bow about a pivot axis formed the engaging second ends of the bow and of the closing part into a second open position in order to open the carabiner in an alternative manner.

Abstract: A carabiner includes a C-shaped, load-bearing hook member and a closing member mounted at an end of the hook member. The closing member can be pivoted in the plane of the hook member and is held in a closing position by the force of a spring. In the closing position, the closing member rests against the other free end of the hook member. A two-arm lever is mounted at the inside of a portion of the hook member adjacent the free end thereof. The two-arm lever is pivotable about an axis extending perpendicularly to the plane of the hook member. The shape of the two-arm lever essentially is the same as the shape of the portion of the hook member adjacent the free end thereof. In the unloaded state of the carabiner, the arm of the two-arm lever adjacent the free end of the hook member rests as a result of the force of a spring against the hook member and an end face of the two-arm lever extends close to the end of the closing member in the closing position.
