The invention relates to a trailer coupling having a support arrangement adapted to be fastened, to a vehicle, on which a bearing is mounted, wherein on the bearing a coupling element is moveable between a use position which is suitable for coupling a trailer to the coupling element, and in which when the trailer coupling is mounted on the motor vehicle the coupling element projects rearwardly of the motor vehicle, and a non-use position in which the coupling element is back behind a bumper of the motor vehicle. On the coupling element, a connecting device for connecting an on-board network of the trailer to an on-board network of the motor vehicle is provided. The connecting device is connectable, to the on-board network of the motor vehicle by a cable comprising a flexible cable section, which at a first longitudinal end is attached to the coupling element in a fixed manner with respect to the carrier arrangement, and at a second longitudinal end is attached to the coupling element in a fixed manner, and which follows the movement of the coupling element between the use and non-use positions. The trailer coupling comprises a winding device for winding a winding section of the cable section onto a cable reel when the coupling element is moved between the use position and the non-use position.
