The flange 3 terminates inside a rim 6 by which the cover is supported on a frame 9. The flange 2 extends below part of the rim 6 and has a horizontal slot 11 at each end in which engages a flange 8 on the frame 9, cut outs 14 accommodating the part 15 of the flange 2. Adjacent one side of the cutouts 14 the flange 8 gradually thickens so that when the cover is turned the slot 11 forms a friction fit with the flange 8.
