ABSTRACT:
A clamping self locking collar includes a split ring, an actuating lever, and a buckle. The lever engages one end of the clamping split ring and the buckle is associated with the other end of the ring. The lever coacts with the buckle in an overcenter manner to positively lock the clamping collar around an article of a predetermined size. The various elements of the collar are produced from a single injection moulding step and are kept together prior to assembly by the inclusion of frangible connections and flexible filaments. No tool is necessary for installation of the clamp or for ensuring safety and intensiveness of the clamping.
