The invention relates to a telescopic device for towing a board for boardsports, in particular a ski, comprising: - a base to be mounted on the board for boardsports; a skid capable of assuming an in-use position in which said skid is positioned spaced apart from said base, and an out-of-use position in which said skid is positioned close to said base; - means for mounting the skid so as to slide relative to said base between the in-use position and the out-of-use position; - means for retaining the skid in the in-use position, comprising a retaining device that is part of the skid and an additional retaining device that is part of the means for slidably mounting the skid. Said device is characterized in that said retaining means are designed to assume an active position for retaining of the skid in the in-use position, wherein said active position is intended for a movement stress which is exerted on the skid in the direction of the out-of-use position thereof and is less than a predetermined stress, and an inactive retaining position intended for a stress that is greater than said predetermined stress. |
