The subject of the invention consists of rectangular leaves (1), the longitudinal sides of which are equipped respectively with tubing, at the ends of which are incorporated elements (5 and 8) - retractile device having a ball with a spring and fixings respectively - for sliding in longitudinal grooves (6) formed in lateral sectional bars (7) which are fixed into a frame (15). Numerous leaves (1) can take their place between the lateral sectional bars (7), those situated at the ends being retained by stops (9) instead and in place of the elements (5 and 8). When a large quantity of information is required, a double-capacity frame is provided, which incorporates at its centre a separation sectional bar (20), the leaves being adjusted between the latter and the respective lateral sectional bar (7). These leaves are capable of incorporating guidance slideways (22) on their front face (2) in order to accommodate display plaques therein. The frame (15) indicated above may be coupled to a support plate (16) suspended from rods; it may also be fixed against a wall, etc. <IMAGE>
