ABSTRACT:
A hose clamp which includes a metallic tightening strap and a tightener that has a housing to which the final portion of the tightening strap is adapted to be fastened as well as a rotatably mounted tightening worm cooperable with a gear tooth system of the tightening strap so as to enable an adjustment of the tightening strap. The final portion of the tightening strap is provided with a bent portion adapted to be inserted into a transverse slit provided in the bottom portion of the housing, with the transverse slit extending substantially at a right angle to the tightening strap. The bent part includes a cross bar which is adapted to be pressed onto a longitudinal wall of the transverse slit by a tension applied to the tightening strap when the tightening strap is tightened.
