The working chamber is in connection with at least one air connection provided in the connection parts. At least one of the connection parts is connected to the associated fastening part by a releasable snap-in or latching connection and the snap-in or latching connection includes at least one air connection, to which a feed line or a hose for the compressed air supply is connected.
