ABSTRACT:
A hose clamping device has a steel clamp band adapted to be tightened around an elastic hose in a ring-like form such that its opposite ends overlap each other. A tightening mechanism is provided on a portion of the band near the underlying end thereof and adapted to pull or push the overlying end, thereby tightening or loosening the band on the hose. A stopper is provided on a portion of the band ahead of the overlying end and is adapted to be contacted by the overlying end, so as to stop the advance of the same. The stopper is constituted by a tab-like portion cut out from a portion of the band and raised in such a manner that the upper surface thereof faces the advance of the overlying end, so as to be pressed down by the overlying end when the latter is pulled by the tightening means. Any excessive tightening by the tightening mechanism only causes the stopper to bend towards the cut out by the pressure applied by the overlying end of the band. Thus, no substantial reduction in the clamping effect is caused by the bending of stopper, thus assuring a stable clamping of the hose on, for example, a pipe end.
