Abstract
A plug-in coupling for systems involving pressurized media, where the coupling consists of two connector parts, a housing part (,) and a connector part (,). The connector part (,) can be inserted into a receiving opening (,) of the housing part (,), while it is being sealed, and when it is in a plugged-in condition, it can be locked in place and prevented from being released by means of a locking device (,). The locking device (,) includes a retaining element (,), which is supported on one side of one of the coupling parts, and which retaining element engages—while in the assembled state—a retaining groove (,) of the other coupling part by means of a form-fit or a form- and friction-fit. A release device (,) is provided in such a manner, that—starting from the assembled state—the retaining element (,) is brought into a release position by means of a further insertion of the connector part (,), in which position the retaining groove (,) is released and the connector part (,) can be removed from the receiving opening (,). The release device (,) is equipped with a sleeve-type locking bar (,), which is capable of relative movement, and which is to be used in conjunction with the retaining groove (,) in such a manner, that the retaining element (,), when it is in the release position, is brought into radial contact with a circumferential area (,) of the locking bar (,) and is thus held in the release position, and when the movement to remove the plug-in connector takes place, the retaining groove (,) is covered by the locking bar (,) and thus closed off in a radial direction from being engaged by the retaining element (,).
