ABSTRACT:
An open clamp structure in which overlapping band portions are mechanically connected by a spring separate from the clamping band; the spring is thereby of low profile having a top portion and lateral portions passing over into mutually facing end portions which are provided with tongue-like extensions adapted to engage in tunnel-shaped embossments in corresponding parts of the clamping band. Means for limiting the extent of stretching to which the spring can be subjected and also providing at the same time a guide function to keep overlapping band portions mutually aligned includes either two tab-like members extending in the longitudinal direction within two narrow slot-like openings only slightly wider than the thickness of the clamping band and of predetermined length or a tunnel-shaped embossment in the inner band portion extending in an elongated opening of only slightly larger width than the embossment to provide the guide function.
