摘要

The sign has a fixation device with an open profile (6) defined by a dorsal wall (10). Two lateral blades (11, 12) and two edges (13, 14) partially close a front inlet of the profile. A screw has a head that slides in a groove of the profile. The profile has grooves (7, 8) that receive screw heads slidingly and lock the heads at rotation, respectively, where one of the screw heads has a section greater than the other screw head.
