An electrical plug-in connection provides a connecting element having an electrically conductive outer housing with a first electrical plug-in connector at a first end that has a ring-segment shaped first contact region, and a first electrical counterpart plug-in connector having contact springs that act via the first contact region to produce electrical contact and a mechanical connection between the first plug-in connector and the first counterpart plug-in connector and the contact springs generate an axial force which acts along a longitudinal axis of the first counterpart plug-in connector which pushes the outer housing against an axial end stop of the first counterpart plug-in connector, and/or the contact springs exert on the first contact region and on a ring-segment shaped, and axially offset, second contact region a radial force, which acts orthogonally with respect to the longitudinal axis of the first counterpart plug-in connector.
