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.

Abstract: A worm-driven hose clamp has a housing made of a band connected with interlocking cutout and projection to form an open butt joint. A clamping screw with a threaded shaft is arranged in the housing. The first and second ends of a clamping strip are overlappingly received in the housing. The first end has thread elements interacting with the threaded shaft. The second end is fastened to the housing bottom which has transverse edges extending transversely to the butt joint. The transverse edges have radially outwardly, circumferentially projecting tongues on opposite sides of the butt joint. The second end has openings on opposite sides of the butt joint for receiving the tongues. Depressions adjoin the openings. They project radially inwardly and extend longitudinally in a circumferential direction of the clamping strip away from the housing relative to the transverse edges. The tongues penetrate the openings and matchingly engage the depressions.
