Abstract 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. By thus making the support hook or hooks such as each to have a substantially greater rigidity in the circumferential direction than that of a suspension hook, the effect is achieved that the circumferentially directed clamping forces that occur during tightening of the clamp are absorbed principally by the support hooks, thus avoiding the bending of the hooks observed in prior art structures and resulting in a firmer clamping effect.
