Abstract
A retaining device has clamping elements arranged on a housing that act as detachable locking elements and can be radially displaced when a pressure member located in the housing is axially displaced. First and second pressure media can act upon the pressure member in the axial direction and the second pressure medium acts upon the pressure member in the opposite direction to the first pressure medium. The retaining device is considerably simplified in that two chambers which follow each other in the axial direction are designed in the housing and separated by a membrane anchored on the housing and having axially movable sections. The pressure member is joined to the membrane and at least one of the chambers can be connected to a pressure medium source.
