Covering panel, especially made from cartoned plasterboard, comprising a first (1) and a second (2) major faces, said major faces (1, 2) being plane and parallel to each other, as well as a first (3, 4) and a second (5, 6) set of adjacent edge surfaces. At least one edge surface in the first set of edge surfaces (3, 4) is plane and forms an acute angle (7) of preferably between 30 and 60 degrees with the first major face (1), and at least the opposite edge surface in the second set of edge surfaces (5, 6) is plane and forms an acute angle (8) of the same magnitude with a second edge surface (2), all in a manner enabling such panels to be secured to a backing or support with the first major face (1) facing the latter, so that at least one edge surface of the first set of plane edge surfaces (3, 4) is secured against the backing or support by the oppositely facing plane edge surface (5, 6) on an adjacent panel having already been secured, so that the panel merely requires to be secured to the backing or support along at least on edge surface in the second set of plane edge surfaces (5, 6). With this arrangement, a secure mutual engagement between adjacent edge surfaces is achieved without substantial weakening of the edges. With particular embodiments, a hidden securing of the panels can also be achieved.
