A temporary closure device for an opening element on a fixed chassis part of a motor vehicle, in which the opening element includes a housing for receiving a lock and the fixed part includes at least one tapped hole for fixing a strike. The device includes a plastic body equipped with means for mounting it in the tapped hole. An end of the device includes a limit stop element that co-operates with a first rim of the housing as the opening element is closed, while another end of the device includes a means for retaining the opening element in the closed position against the fixed part, which is intended to penetrate the housing behind a second rim thereof. The retaining means is formed by a resilient tongue, which can bend under stress from the second rim when the opening element is moved from the free position to the closed position.
