The device has a releasing device (4) provided with a set of functional parts (8, 10). An adjusting body (14) is fixed radially outward of a clamping body (12) against movement, so that the clamping body supports the functional parts in axial direction. The adjusting body exhibits a round cross section and maximum radial extension in a function position, and is rotatable around rotation axis by an actuating element (18) e.g. adjusting ring (16), with reduced radial extension in another function position, so that the clamping body is movable radially outward. |
