Abstract
Abstract A one piece clamping device which includes a proximal flexible hinge portion, distal portions having non-penetrating substantially flat gripping surfaces, and male and female medial portions. The male medial portion has a male locking member, one surface of which is toothed and the other surface of which is non-toothed. The female medial portion has a female locking cavity and a locking ledge extending therein. The toothed surface of the male locking member thereby meshes with the locking ledges of the female cavity. The male medial portion also includes a male guide, and the female medial portion also include a female guide channel for receiving the guide and a spur to guide the non-toothed surface of the male locking member into position in the female cavity and to retain it.
