Abstract
An elastomeric sealing sleeve 6 is enclosed by an annular housing 1 which is split longitudinally and can be drawn together in the peripheral direction by means of a clamping screw 22. The clamping screw 22 passes with clearance through two U-shaped clamping members 16, 17 which are accommodated in clamping brackets 12, 13 fastened to the housing 1. The clamping members 16, 17 are supported with the ends of their legs on flat wall sections 12a, 13a of the clamping brackets 12, 13. The head 24 as well as a nut 25 of the clamping screw 22 bear against arched supporting surfaces 20a of the clamping members 16, 17. While the housing 1 is being drawn together, the clamping members 16, 17 can move relative to the shank 23 of the clamping screw 22, in the course of which the screw head 24 and the nut 25 can roll on the arched outer surface 20a. The screw shank 23 is therefore subjected to little or no bending stress.
