<p>The frame cover, comprising a plane bearing plate (24) provided with two lateral flaps (28, 30) folded over at right angles towards the top, a plane upper plate (26) provided with two lateral flanges (32, 34) folded over at right angles towards the bottom, the upper plate being intended to be assembled to the bearing plate in such a way that the flanges are received between the flaps and the upper plate and the bearing plate enclosing a parallelepipedal volume of dimensions slightly greater than the frame to be covered, is characterised in that it further comprises several vertical locking strips (40) intended to keep the bearing plate and the upper plate assembled, the said strips comprising two vertical wings (42, 44) separated by a slit (46) capable of receiving together the lateral edges of the flanges and of the flaps together with one edge of a vertical lateral upright (20, 22) of the frame. <IMAGE></p> |
