The invention provides a moulding of foam synthetic resin for hiding the angle zone between the wall and the ceiling or between the wall and the floor of a room, which to the rear has a retainer profile (7 and 8), into which the lugs (9 and 10) on the fittings (1) fit. The fittings (1) secured in the angle zone between the wall and the ceiling thus bear the moulding (2) and the arrangement in accordance with the invention consisting of the moulding (2) and the fittings (1) may also constitute the border of a suspended ceiling adjacent to the walls and in this respect simultaneously perform a load bearing function as regards the ceiling edge elements of the suspended ceiling. The suspended ceiling may be a coffered ceiling, whose coffer frame are constituted by the mouldings (2). The angles constituted by two respective mouldings of a coffer frame are held together by means of angle fittings or, respectively, resilient staples.
