The invention relates to a plug connection (14) for the common coupling of electric and fluidic lines (34, 35), combined in a bundled run (10), to the corresponding lines (34, 35) of another bundled run (11). It is preferably used in underground mine operation, e.g. in the electric and hydraulic cabling of a suspension rail conveying system, in order to be able to better utilise the restricted space available here. Individual lines are no longer combined, so that in the case of several electric and fluidic consumers the hitherto necessary individual couplings are omitted. The plug connection (14) has two coupling housings (15, 16) which can be screwed to one another and have receiving bodies (17, 21) in which the ends of the electric and fluidic lines (34, 35) of the bundled runs (10 and 11) to be coupled to one another are secured. On the coupling gap side, the receiving bodies (17, 21) have plug contacts (46, 47; 76, 80) for transferring the electric and fluidic power. In addition, the plug connection (14) is provided with safety valves (86, 89) for reducing the pressure increase caused in the event of a backpressure. <IMAGE>
