Abstract:
1. A worm drive hose clip comprising: a clamping strap having overlapping end sections; a clamping screw comprised of a head and a threaded shaft; a housing enclosing the overlapping end sections and the threaded shaft of the clamping screw; wherein a radially outwardly positioned one of the overlapping end sections is provided with thread elements engaging the threaded shaft; wherein the radially inwardly positioned one of the overlapping end sections is positive-lockingly connected to a bottom of the housing, wherein the housing supports the clamping screw in a circumferential direction of the worm drive hose clip; wherein the housing is comprised of a housing band having ends, wherein the ends are connected to form a butt joint at the bottom of the housing and have edges delimiting the butt joint, wherein the edges have undercuts interlocked with one another to secure the butt joint; wherein the bottom of the housing has a first transverse border facing the head and the first transverse border has a tongue, respectively, on opposite sides of the butt joint, wherein the tongues are radially outwardly bent and project together into an opening provided in the radially inner end section of the clamping strap; wherein the bottom of the housing facing away from the head of the clamping screw has a second transverse border of a continuous straight configuration; wherein the clamping strap has first grooves pressed radially inwardly out of the clamping strap; wherein the second transverse border is supported on the first grooves and wherein the first grooves open toward the second transverse border; wherein the clamping strap has a second groove adjoining the opening common to the tongues and arranged proximal to the head, wherein the second groove is open toward the bottom and wherein the bottom is supported on the second groove; wherein the radially inner end section of the clamping strap is free of a radially outwardly oriented bent portion for receiving the bottom; wherein the first and second grooves extend in the circumferential direction of the worm drive hose clip and wherein a radially inner edge of each one of the first and second grooves is aligned with an underside of the bottom and has a continuous transition into an inner side of the radially inner end section.
