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.
