Abstract

A karabiner comprises a generally C-shaped body the ends of which are joined by a pivoting finger, articulated at a first end and engaging at its second end with the free end of the body. The corresponding engagement ends of the finger and of the body include a male end shape and a female end shape. The male end shape has a thinner portion carrying at least one lateral protuberance and engages in a slot in the female end shape. The lateral protuberance engages in a corresponding lateral housing of the slot shaped to restrict axial relative displacement of the end shapes and to prevent the karabiner finger opening when the body is under axial traction load. A shape of this kind has no hook-shape part, and combines the functions of contributing to withstanding axial traction loads and dynamic locking on application of axial traction loads to the karabiner body.
