Abstract

A worm drive hose clip has a clamping strap with overlapping end sections, a clamping screw, and a housing. The radially outer end section has thread elements engaging the threaded screw shaft. The radially inner end section is connected to the housing bottom having a butt joint with interlocking undercuts. The bottom has a first transverse border with tongues arranged on opposite sides of the butt joint and projecting outwardly into an opening of the radially inner end section. A second straight transverse border of the bottom is supported on first grooves impressed radially inwardly in the clamping strap and opening toward the second transverse border. A second groove adjoins the opening and supports the bottom. The radially inner edges of the first and second circumferential grooves are aligned with an underside of the bottom and pass continuously into an inner side of the radially inner end section.
