<p>The system has rails (16) fixed between successive vertical rail posts (12). The rails are in the form of horizontal bars, where each rail comprises flanges (17) at its ends (22). The flanges are projected with respect to the periphery of the rails, and axially retain the rails on the corresponding rail posts equipped with locking units (20), irrespective of the angular position of the rails. The locking units lock the adjacent ends of two rails by wedging.</p> |
