The stop mechanism includes a circular, ring-shaped housing (2) in which a polygonal body (3) fits rotatably, and with which the tightening part (6) is rigidly connected. Between the polygonal body and the housing inner wall (7) is fitted a running ring (8) provided with stop units. - The stop units (9), through rotating of the running ring, are movable towards the corner of the polygonal body (3). With sufficiently extensive tion of the running ring (8) these locate against both the inner wall (7) of the housing and the body sides (11), locking by wedge effect the polygonal body in the housing. |
