ABSTRACT:
A slalom post (1) is described at the bottom end of which an anchoring element (3) shaped as a flange (3) is provided collaborating with a protection wedge (7). The flange (3) may be moved from a non-effective position when the flange (3) is within the profile of the protection wedge (7) into an effective position when it projects beyond the profile of the slalom post. In this way, a structurally simple, easily operable and very effective anchoring of the slalom post is obtained.
