A closure device for closing an aperture in a panel includes a plate and plural retaining tabs extending from one face of the plate. The tabs have first and second lips which cooperate with the panel adjacent the aperture for centrally locating and locking the closure device in position. The plate also includes a cup-shaped central region which extends outwardly from the plate at least as far as the plural tabs to reduce the potential for any injury or damage from the tabs. A seal member is interposed between the closure device and panel for effectively sealing therebetween.
