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. The other arm of the lever is spaced apart from the portion of the hook member opposite this other arm. When the lever is pivoted, the end face of the arm adjacent the free end of the hook member extends into the pivoting range of the free end of the closing member in the closing position thereof and, as a result, locks the closing member in the closing position thereof.
