The invention relates to a plug-in connector, in particular for an optical waveguide, comprising a jack housing (1) which is located at one end of an optical waveguide (not illustrated) and a pin cover strip (2), provided for receiving the jack housing (1). A play-compensating element (3) is located on the jack housing (1) and/or pin cover strip (2). An optical plug-in connector of this type minimises axial play between the jack housing (1) and the pin cover strip (2), by means of the play-compensating element (3).
