Plug-in coupling for pressure lines, consisting of a plug part (1) having a through-hole (2) and of a screw-in body (3) having an external thread (4) and a through-hole (5) for holding a plug spigot (6) of the plug part (1), the screw-in body (3) being capable of being screwed into a threaded hole (7) of a housing body (8), and consisting of latching means for fixing the plug part (1) in the housing body (8), of a spring element, which is arranged between the plug spigot (6) and the housing body (8) and acts in the axial direction, and of a radial seal between these two parts, the latching means consisting of spring arms (9) which are constructed on the insertion end of the plug spigot (6), run in the longitudinal direction of said spigot, are flexible in the radial direction and have an outwardly directed stop surface (10) which, in the inserted state of the plug part (1), engage behind (seen in the insertion direction) an annular surface (11) (running towards the interior) inside the housing body (8), preferably on the screw-in body (3), and the radial seal and spring element are arranged in front of (seen in the insertion direction) the spring arms (9). <IMAGE>
