In this plate comprising a front profiled part, a rear profiled part and intermediate profiled parts 23, all the profiled parts are arranged parallel to one another and each profiled part is fixed to each adjacent profiled part by an upper pair of complementary linking elements 24, 27 and by a lower pair of complementary linking elements 26, 28. The upper pair comprises a partially cylindrical rib 24 forming an articulation axis 25 and a partially cyindrical groove 27 open upwards and capable of receiving, in a pivoting manner, the rib 24 of an adjacent profiled part. The lower pair comprises a rib 26 and a groove 28 capable of receiving, by elastic interlocking, the rib 26 of an adjacent profiled part when two adjacent profiled parts are made to pivot relative to one another about the articulation formed by a rib 24 and by a groove 27. <IMAGE>
