1. A plug-in connection, comprising:

  • a socket including;

    a housing which is composed of electrically insulating material and has an elongate plug-receiving region;

    a contact spring which is arranged in the plug-receiving region; and

    a lever which, in an open position, tensions the contact spring, so that a dimension of the contact spring transverse to a longitudinal direction of the plug-receiving region is reduced, and which, in a closed position, relieves the contact spring of tension relative to the tensioned state, anda plug having an electrically insulated housing and a clearance into which the contact spring of the socket is insertable when the plug is inserted into the socket, andwherein the contact spring is dimensioned such that, when the lever is in the open position and as a result the contact spring is tensioned, the contact spring is insertable into the clearance in the plug, and, when the lever is in the closed position, the contact spring presses against an electrically conductive inner face of the clearance of the plug.
