• the base body comprises a plugging side and a connecting side, the plugging side being configured to interface with a mating plug connector, and the connecting side being configured to receive an electrical cable;
• the plug connector forms a plugging axis that extends from the plugging side to the connecting side through the plug connector;
• the sliding element is arranged on said base body in such a manner that said sliding element is able to move along the plugging axis;
• the plug connector comprises a securing element, wherein the securing element is arranged between the sliding element and the connecting side of the plug connector;
• the securing element is arranged to move on the base body between an open position, in which the sliding element is able to move along the plugging axis in a direction toward the connecting side, and a locked position, in which the sliding element is blocked by the securing element from moving along the plugging axis in the direction toward the connecting side;
• and
• the securing element is configured to lie within an inner peripheral edge of the sliding element when the securing element is in the open position such that the sliding element is able to move past the securing element when moving in the direction toward the connecting side.
