The slot extends in a circumferential direction along the clamp. The radial inner end portion has a projection and a second closure element, which when closing the clamp comes into a locking mechanism engagement with the first closure-element. The projection can be inserted into the slot and can be locked in this position. In order to avoid the danger of locking the projection at its insertion into the slot, and to assure that the end portions retain their required relative position when applying tension to the clamp, the projection is a circumferentially extending bar and the slot has a pair of flaps on opposite edges of the slot and protruding into the slot. The bar has notches which are provided for the radial passing of the flaps and the bar is shorter than the slot of the clamp in a circumferential direction. | |
