Abstract: A releasable plug-in connector for receiving a tubular plug-in part having a peripheral retaining rib. The plug-in connector consists of a housing having a cylindrical receiving space for receiving the plug-in part, and a separate securing ring made from a hard/resilient plastic material. The ring has retaining edges directed inwardly in the form of an arc of a circle that are pushed apart as the plug-in part is pushed into the connector and that then spring back elastically and engage behind the retaining rib after the plug-in part has been pushed in to lock the part in the connector. The retaining edges are connected to one another at their ends by a pair of V-shaped spring webs that are accessible from the outside of the housing so that they can be pushed into an unlocked position permitting the part to be pulled out of the connector.

Abstract: A fluid coupling wherein a tubular coupling member has a first terminal sealingly engageable with an end of a first conduit and a second terminal sealing engageable with an end of a second conduit. The end of the second conduit has a radially outwardly extending retaining flange and the coupling member has a set of radially movable resilient arms which engage the flange when the second terminal is in proper engagement with the end of the second conduit. The arms can be prevented from becoming accidentally disengaged from the flange by one end portion of a sleeve which is reciprocable along and surrounds the coupling member. The sleeve can be releasably locked in a release position in which the arms are free to become disengaged from the flange and/or in a locking position in which the sleeve prevents disengagement of the arms from the flange.

Abstract: A locking device for a plug-in connection between a fluid pipe, provided with a shaped-on radially protruding abutment, and a connecting part utilizes a clamp, which can be guided in the connecting part, two branches of the clamp overlapping the abutment of a correctly plugged-in fluid pipe in order to secure the plug-in connection against axial separation.
