Abstract
A cover assembly for an opening comprises a frame and a covering. At least one elastically deformable, rod-like closing member is provided on the covering. The closing member forms one part of a locking device, the other part of which is a retaining member which includes a groove provided in the frame, in which can engage a closing finger located on the closing member accompanied by the elastic deformation of the closing member. Thus, in a simple manner, the covering is positively secured in the frame.
