A method for producing a plug-in connector includes stripping a cable on a free end in a first and second region of a sheath of the cable, where a shield is disposed below the sheath on the cable. The method includes disposing a first electrically conductive spring element in the first region, and removing the sheath and the shield from the second region, thereby forming an end portion of the free end of the cable on which exposed wires of the cable are disposed. The method includes disposing contact elements on the exposed wires, and disposing a shield sleeve around the first electrically conductive spring element. The method includes fastening the shield sleeve on the sheath before and after the first electrically conductive spring element, and providing an insulating housing such that the insulating housing at least partially surrounds the shield sleeve and the free end of the cable.
