<p>A clamp structure consists of a clamping band having open ends that are mechanically interconnected by outwardly extending hooks in an inner band portion operable to engage in corresponding apertures provided in an outer band portion. The clamp structure includes a device for tightening the clamping band about an object to be fastened. The invention is characterized by a tongue at a free end of the inner band portion. This tongue is operable to engage into a tongue-receiving slot located at least within the area of an outwardly extending step-like portion provided in the outer band portion. This arrangement assures a substantially gap-free and stepless transition in the circumferential direction from the inner band portion to the ring-like configuration of the clamp structure defined by the clamping band upon tightening of the clamp structure.</p> |
