1. An electrical plug-in connection, comprising: a plug part accommodating one or more contact pins; a socket part accommodating one or more socket contacts, wherein said contact pins are plugged into said socket contacts when the plug-in connection is closed; coding elements on said plug part and on said socket part and configured to interact in accordance with a lock/key principle in order for said plug and socket parts to be fixed in place in a pre-defined plug-in position in relation to one another; one or more protrusions and complementary apertures on said plug and socket parts, respectively, such that in each case one protrusion is disposed in a respective said aperture, engaging behind a periphery of the associated aperture in the process, and that said aperture has two accommodating chambers arranged one beside the other; wherein a periphery of the one plug-in accommodating chamber, said periphery being directed away from a plug-in direction, is at such a low level that an associated said protrusion slides over said periphery in the plug-in direction; and wherein a periphery of the arresting accommodating chamber disposed adjacent said plug-in accommodating chamber, is at such a high level to effectively prevent a sliding of said protrusion over said periphery of said arresting accommodating chamber.
