ABSTRACT:
A self-retightening screw-type clamp with predetermined adjusting range for a given clamp size, attained by a predetermined number of apertures provided in the inner band portion of a separate band part in conjunction with a sleeve member of predetermined length interposed between the retightening spring and a part-cylindrical tightening member. The full adjusting range of the screw member is made possible by deforming the threads near its free end. Additionally, to facilitate assembly, the inner band portion of the separate band part is provided with a tongue-like extension which is adapted to engage with a latching device formed in the clamping band so as to hold the tongue-like extension of the inner band portion of the separate clamping band part at least close to the outer surface of the clamping band.
