The clamping device has inner and outer overlap portions of the clamp band made of metal strip material forced by an operating tool to close until the seizing tooth of the inner overlap portion and the fixed tooth of the outer overlap portion seize each other to contract the bore dia. of the clamp band. The assembly is locked by a prop key extending from the outer overlap portion to engage the inner overlap portion. An elastic hump for storing the spring force acting circumferentially of the clamp band is outwardly bulged from the outer overlap portion. |
