A plug or closure for closing and substantially sealing an aperture in a vehicle body panel. The plug comprises a plate portion and a resilient spring element carrying a plurality of resilient snap-engaging legs. The plate portion and the spring are separate and can be formed from different materials. The plate portion has an undersurface and one or more bosses in the undersurface defining a plurality of side walls. The spring has a body integral with the legs defining a plurality of edges and the spring is attached to the plate by forcing the body of the spring between or over the bosses or boss respectively so that the edges of the body of the spring frictionally engage the side walls of the boss or bosses. The plug may be provided with a ring of sealing material on the periphery of the undersurface of the plate.
A plug for closing an aperture in a panel comprising a generally flat metal plate adapted to cover the aperture in the panel, an undersurface on the plate, at least one boss in the undersurface of the plate defining at least two spaced sidewall portions, a resilient metal spring comprising a body portion attached to the undersurface of the plate and at least two resilient legs depending from the undersurface of the plate and adapted for snapengagement through the aperture in the panel, wherein the body portion is provided with at least two spaced edge portions in frictional engagement with the said at least two spaced sidewall portions of the boss to retain the spring and the plate together.
