The invention relates to a plug-in coupling for fluid systems having two coupling parts connectable to one another, which each have coordinated catches for connecting them together, one of the coupling parts having an end union section, by means of which it can be plugged into the other coupling part, and one of the coupling parts having at least one end retaining section carrying its catches, by means of which section it grips over an outer peripheral contour of the other coupling part, on which the coordinated complementary catches are formed. In order to achieve a simplified means of detachment whilst ensuring ease of assembly and a highly stable connection of such a plug-in coupling, it is proposed to provide a separate release part, which in the assembled state is held on the first coupling part and/or the second coupling part and which serves for separating the locking connection between the catches of the first coupling part and the catches of the second coupling part.
