The device has a covering surface, and a support (4) on longitudinal edges of a bath-tub (19). The covering surface is formed by association of a pair of sections (1a, 1b) connected by articulation units directed along a longitudinal direction of the bath-tub. The articulation units are made by an elongated support (2) on which is mounted the pair of sections (1a, 1b) on its both sides. |
