The arrangement is intended for fixing various interchangeable sign boards (2), such as may be used for traffic signs, temporary road markings, or for traffic instruction purposes. It comprises a base (9) with an upright projection capable of engaging a corresponding recess in the lower end of a post (8) whose upper end has a smaller-size stepped down (7) upward projection (6) which, in turn, can engage a recess (5) in a coupling member (4) fixed to the board (2). The coupling member also has a smaller-size stepped down (3) upward projection (1) and extension members are provided, one type having a recess at either end and another type having smaller-size stepped down projections at either end, all projections and recesses having complementary dimensions. |
