Abstract: A connection arrangement for filling and draining a liquid includes a sealing element arrangement and a joining arrangement. The sealing element is movable between a closed position and an open position. A filling passage of the connection arrangement is defined by at least one of the sealing element arrangement or the joining arrangement. A draining passage of the connection arrangement is definable by the sealing element arrangement and the joining arrangement, the draining passage being adjustable by moving the sealing element arrangement between the closed position and the open position.

Abstract: A vehicle component (1, 17, 31, 46, 55, 62) for a motor vehicle, with a structural component (7, 16, 30) and with a casing (2, 18, 32, 38, 56, 57, 79). The structural component (7, 16, 30) is at least partially or completely overmolded and/or embedded by casting in order to form the casing (2, 18, 32, 38, 56, 57, 79). To avoid any interruption of the casing (2, 18, 32, 38, 56, 57, 79) and/or interruption of corrosion protection in the area of the holding point (8), a holding point covering (12, 15, 39, 36, 45, 54, 61) is arranged at a holding point (8) for holding the structural component (7, 16, 30) in an injection-molding die and/or a casting mold.
