ABSTRACT:
A clamp structure with a clamping band whose ends are drawn together by a screw-type tightening 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 tightening members; one of the band tightening members is of at least semi-circular shape and is retained in a loop-like pocket formed by an end portion of the clamping band externally bent back upon itself and secured to the underlying band portion while the other tightening member also of at least semi-cylindrical shape is retained in a loop-like pocket formed by a separate clamping band part whereby the two loop-like pockets are spaced from one another defining a gap; a stepless internal configuration of the clamping surfaces of the clamping band is assured by a tongue-like extension at the inner band portion adapted to engage in a channel-like indentation provided in the outer clamping band portion; to reliably prevent the inner band portion from bulging out into the gap underneath the screw-type tightening mechanism, a separate reinforcing part is provided underneath the gap which on both sides of the gap extends between the inner and outer band portions; the reinforcing part simultaneously performs a guide function to keep the inner and outer band portions aligned in the axial direction.
