In an electrical connector, one half of a least one contact carrier, a shield cover for a cable and contact portions receiving housing which is provided for securing the connector to a second connector half with an internally threaded coupling nut, and wherein the sleeve nut over an axial distance from one another formed on the housing, sliding bearing portions formed by radially projecting annular webs but is supported to the housing longitudinal axis rotatable in the axial direction non-displaceably on the housing, is provided to secure the nut against unintentional rotation in the release direction, that the securing spaced-apart in a between two in the axial direction, by plain bearing areas formed radially projecting annular webs of the housing located free annular space is accommodated and on a part housing or nut circumferentially extending Sägeverzahnu ng and at least one with this cooperating spring-loaded latching lug, said latching lug the spring loading load is small such that the intended retention effect is mainly achieved by the steepness of the interacting tooth flanks in the release direction
