Abstract: A closure cover is formed of plastic and intended for closing an opening in a panel, such as a wall or floor panel of a motor vehicle. The closure cover includes a cover plate sized to overlie the opening and having a multiplicity of resilient holding elements depending therefrom to extend through the opening adjacent the periphery thereof. The holding elements include jaw portions extending laterally to engage under the periphery of the opening. The jaw portions of adjacent holding elements are located at different distances from the cover plate. Preferably the locations of the jaw elements describe a plurality of continuous curves relative to the cover plate to allow the same closure cover to be used on panels of a range of thicknesses.
