International ClassF16L 033/02Foreign Application Priority Data1993-05-19 FRAbstractA clamp fitting is formed by an internal segment of metal band wound upon itself, and an external segment of metal band formed about a portion of the internal segment. The internal segment extends for more than one complete circumference such that the outer end of the internal segment overlaps the internal end of the internal segment to form a continuous internal surface. The outer end of the internal segment presents an ear formed by two folds of band placed back to back and projecting radially on the outer periphery of the clamp. The external band segment extends only for a partial circumference. One end of the external segment is attached to the outer face of the internal segment. The other end of the external segment is shaped as a hook capable of hooking behind the ear to maintain the clamp in a tightened position. | |
