Abstract: An integral cable fastener having two parallel legs joined on one end by an integral cross member or bridge to form a curved cable engagement surface, the free ends of the legs having end barbs formed by sloping surfaces, and having transverse withdrawal resisting shoulders. Ribs on the concave inner surface of the bridge secure the cable against linear or lateral movement. Transverse drive surfaces on the bridge are axially aligned with the legs and barbs. Insertion depth control shoulders on the legs limit depth of insertion to a predetermined value.
