An open reusable clamp structure, especially of the earless type, with a clamping band having overlapping inner and outer band portions adapted to be detachably interconnected by mechanical connecting means; first tool-engaging surfaces are provided in the inner and outer band portions, preferably in the form of pressed-out cold-deformed embossments for tightening the clamping band about an object to be fastened thereby, and second tool-engaging surfaces are provided in the inner and outer band portions which are separate from the first tool-engaging surfaces and are again preferably in the form of pressed-out cold-deformed embossments for reopening the previously interconnected overlapping band portions. To prevent over-torquing during reopening, undulations or the like are provided in the outer band portion intermediate the first and second tool-engaging surfaces. |
