Abstract: The housing of the cable plug is exclusively formed of a one-piece metal part bent U-shaped which presses against the unit equipped with the contact spring elements under spring tension. In order for a shielding elimination to ensue on a short, direct path to a grounded potential carrier, the legs of the metal part nearly surround the unit or they even extend beyond it. In such a case, they are executed as resilient tongues with which an electrical connection to the grounded potential carrier directly ensues. Catch elements are provided for an interlocking connection of the metal part to the unit containing the spring clips or the blade strips. The web surface of the metal part proceeds at a slant relative to the bottom edges of its legs. In order to enable an oblique exit of the cable both toward the top and bottom, as well as toward the right and left, the said unit can also be engaged side-inverted without loss of positioning.
