To transmit the shielding potential of an electric cable that is connected to a circular connector and surrounded by a braided shield to a mating connector, a circular connector includes a shield transfer element comprising an insulation displacement connector, a transfer contact and a spring bow in the connector housing of the circuit connector. The spring bow contacts the electrically conductive screw cap arranged on the outside of the connector housing through an opening provided in the connector housing while the transfer contact contacts a neutral wire of the circular connector in the center of the circular connector. The braided shield is connected to the shield transfer element by the insulation displacement connector.
