ABSTRACT:
A self-locking snap-hook is disclosed which is so shaped that the tractive load transmitted by a first traction element is applied to a first tractive force application end formed by the snap-hook body, and the tractive load transmitted by the second traction element is applied to the locking finger. Thus, the application of the tractive load tends to close the snap-hook and cause self-locking thereof.
