Abstract

The invention pertains to a plug connection for pressure systems which consists of two coupling parts, namely a receptacle part (2) and a plug part (4). The plug part (4) can be inserted into a receptacle opening (8) of the receptacle part (2) with a plug shaft (6) such that it is circumferentially sealed and blocked from being separated by a locking device (12). The locking device (12) is realized in such a way that a partially plugged prelocking position (FIG. 1b) and an entirely plugged full locking position (FIG. 1a) are ensured. In the prelocking position, an incomplete seal is produced such that a signal, preferably an acoustically perceivable leakage noise, is generated if the plug connection is charged with pressure. A complete, pressure-tight seal is produced in the full locking position. The locking device (12) comprises a holding element (20) that is situated in a recess (22) of one coupling part (2) and realized in such a way that it respectively engages behind the same locking edge (24) of the other locking part (4) in the prelocking position (FIG. 1b) as well as in the full locking position (FIG. 1a).
