The device has a rectangular shaped base (2) with median and lateral elongated openings (6, 7) that are situated at a distance from each other. A spacer (4) includes a portion (11) forming a clean spacer connected to a sign panel (3). The spacer has an extension (12), which is not connected to the panel, extending the portion from a side of the base, where the extension is folded with respect to the portion. The extension is engaged through the opening (6), folded against the base, and is engaged through the opening (7) by slight deformation to lock the extension in unfolding position. |
