ABSTRACT:
A hose clamp with a clamping band having two ends which are drawn together by a screw-type mechanism that includes a first band-tightening member secured near one band end, a second band-tightening member secured near the other band end, and a screw member for drawing together the first and second members; one of these band-tightening members is thereby securely held in place by an end portion of the clamping band externally bent back upon itself and secured to the underlying band portion while the other member is retained by a separate band part which is also externally bent back upon itself with the outer bent-back end portion secured to the underlying band portion of the separate part while the latter is secured to the clamping band itself; to assure a stepless internal configuration of the clamping surfaces of the clamping band, the inner end of the clamping band terminates in a tongue-like extension adapted to engage in a groove-like indentation provided near the other end of the clamping band.
