ABSTRACT:
For obtaining a hose clamp which has a continuously smooth inner surface free of gaps and which requires an as short as possible length of band material, the inner band end portion is provided with a tongue the length of which is approximately half the amount by which the hose clamp is narrowed during tightening. During the first half of the tightening movement, the tongue is guided transversely to the band longitudinal direction by a projection which engages a slot provided in the outer band portion. The slot at its end is continued by a window which starts at a step, and the tongue, during the second half of the tightening movement, passes through the window which then takes over the guidance of the tongue.
