1. A system for conductively charging a motor vehicle, comprising:
a charging device having a contacting unit and a lifting device operable for axially moving the contacting unit between retracted and extended positions;
a receiving device having a receiving chamber for receiving the contacting unit inserted therein when the contacting unit is moved to an extended position;
wherein the contacting unit has a cylindrical or truncated cone body and includes an electrical contact ring extending around a lateral surface of the body of the contacting unit; and
the receiving device includes a radially position-able electrical contact element along the receiving chamber, the contact element is mechanically connected to an elastic loop and is radially position-able between radial positions by the elastic loop being relaxed and tensed, and in one of the radial positions while the contacting unit is inserted into the receiving chamber, the contact element electrically contacts the contact ring and mechanically fixes the contacting unit to the receiving device inside the receiving chamber.
