Abstract: The telescopic device for towing a board for board sports includes a base mounted on the board; and a skid with an in-use position positioned spaced apart from the base, and an out-of-use position positioned close to the base. There is a mechanism for mounting the skid so as to slide relative to the base between the in-use position and the out-of-use position and mechanism for retaining the skid in the in-use position, that includes part of the skid and an additional retaining device that is part of the mechanism for mounting the skid. The mechanism for retaining has an active position for holding the skid in the in-use position. The active position is intended for a movement stress, which is exerted on the skid in the direction of the out-of-use position. There is an inactive retaining position intended for a stress that is greater than a predetermined stress.
