A clamp structure with a clamping band having open ends adapted to be mechanically interconnected by outwardly extending hooks in an inner band portion operable to engage in corresponding apertures provided in an outer band portion; at least one plastically deformable ear is provided in the clamp structure for tightening the clamping band about an object to be fastened by plastic deformation of the ear; a substantially gap-free transition in the circumferential direction from the inner band portion to the ring-like configuration of the clamp structure defined by the clamping band is obtained by the use of a tongue-like extension at the free end of the inner band portion which is operable to engage into a tongue-receiving aperture or channel provided in the outer band portion. In one embodiment, the mechanical connection consists of one suspension hook of tab-like configuration and one or more support hooks realized by cold-deformation and separated from the remaining band material by only a substantially transversely extending cut.

A clamp structure, comprising clamping band means having open ends, means mechanically interconnecting the open ends of the band means including outwardly extending hook means in an inner band portion operable to engage in corresponding aperture means provided in an outer band portion, and at least one means in the clamp structure for tightening the clamping band means about an object to be fastened, characterized by a tongue means at the free end of the inner band portion, which is operable to engage into a tongue-receiving means provided at least within the area of an outwardly extending step-like portion provided in the outer band portion to assure 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 band means upon tightening of the clamp structure by said tightening means, the tongue-receiving means being a channel-shaped pressed-out recess within the center area of the band means substantially formed as a circumferential continuation of the outwardly displaced outer band portion leaving lateral band portions on both sides of the channel-shaped recess, the step -like portion being formed in the lateral band portions so that the lateral band portions pass over to the radial height of the channel-shaped recess.
