Abstract

A cylinder has a coupling portion with a coupling ring and a locking body. A cylinder tube has an inner annular groove and a closure part is disposed in a tube end portion and has an outer annular groove axially open at one side. The annular grooves define an annular groove space that receives a coupling ring. The ring is segmented into a plurality of ring segments. The ring segments abut one another at separating cuts and are configured parallel to one another or open in a concentric direction. The closure part is secured at one axial end by the ring. The locking body is arranged on the closure part and has a circumferential ring surface that defines a pressure contact with the ring and form-fittingly secures the ring in the groove space. The locking body secures the closure part at one axial end by pressure contact with the ring.
