An electrical connector is provided for terminating a cable having a cable shield. The deformation generally is an analytic function of the tension in the fastener. In order to achieve as flat a design as possible, the restoring force is transmitted with the aid of a pivotable lever via a front bearing pin to a first front joint pin, an active lever length which can be varied with the aid of an adjusting element being defined by the spacing between the bearing pin and the second front joint pin. In addition, the latching assembly includes an inner component positioned adjacent to the housing and an outer component positioned adjacent to the inner component. The lid has a monitoring unit and permits the flow of water into and out from the tank. The flange portion and a peripheral portion of the wide mouth are formed by injection molding and not drawn after the injection molding is carried out.
