The profiles 3 and 4 which make up the frame 1 of the panel 2 proper supporting the items to be displayed are joined via their ends by means of linking connections which allow the displacement of the profiles 3 in terms of separation and of the upper profile 4 in terms of elevation, in order to obtain a free movement (play) 5 6 which allows the frontal removal of the panel 2, so that it can be exchanged, it being possible for the original structure of said frame 1 to be reestablished by means of the reverse operation. <IMAGE>
