ABSTRACT:
A draw operating type clamping device wherein an elastic hump is outwardly bulged from an outer overlap portion of a clamp band to serve as a tension spring element. The device includes an elastic hump taken to be a boundary and at a position reverse to a locking location where the seizing tooth of the inner overlap portion and the fixed tooth of the outer overlap portion of the camp band seizingly engage each other, there are a preparatory seizing tooth outwardly bulged from the inner overlap portion and a preparatory fixed tooth inwardly bulged from the outer overlap portion, so that if a stretch deforming force exceeding the elastic limit should act on the elastic hump, the preparatory seizing tooth and preparatory fixed tooth are brought into seizure engagement with each other, thereby eliminating the danger of the clamp band being loosened.
