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.

1. A device for towing a board, said device comprising: a base;a skid being in sliding engagement with said base and being comprised of a guiding part and a guided part, said guiding part being connected to said base and between said base and said guided part,wherein said skid has a first position and a second position, wherein said first position corresponds to an in-use position, wherein said guided part of said skid is positioned spaced apart from said base in said first position, wherein said second position corresponds to an out-of-use position, and wherein said guided part of said skid is positioned closer to said base in said second position than in said first position; andmeans for sliding said skid between said first position and said second position; andmeans for retaining said skid in said first position,wherein said means for retaining said skid in said first position has an active retaining position corresponding to snap fit engagement,wherein said snap fit engagement in said active retaining position has a determined retaining stress greater than a displacement retaining stress in a direction from said first position to said second position,wherein said means for retaining said skid in said first position has a released retaining position or out-of-use position corresponding to release of said snap fit engagement in said active retaining position, andwherein said determined retaining stress is less than said displacement retaining stress in said released retaining position. 2. The device for towing, according to claim 1, further comprising: means for holding said skid said second position,wherein said means for holding said skid in said second position has an active holding position corresponding to snap fit engagement,wherein said snap fit engagement in said active holding position has a determined holding stress greater that a displacement holding stress in a direction from said second position to said first position,wherein said means for retaining said skid in said second position has a released holding position corresponding to release of said snap fit engagement in said active holding position, andwherein said determined holding stress is less than said displacement holding stress in said released holding position. 3. The device for towing, according to claim 2, wherein said active holding position of said means for holding said skid in said second position corresponds to retracted engagement. 4. The device for towing, according to claim 3, wherein said snap fit engagement is comprised of a notch and lug engagement. 5. The device for towing, according to claim 2, wherein said active holding position of said means for holding said skid in said second position corresponds to retracted engagement. 6. The device for towing, according to claim 5, wherein said retracted engagement is comprised of a notch and lug engagement. 7. The device for towing, according to claim 1, further comprising: a rolling means, said guided part of said skid being between said base and said rolling means,wherein said skid has a free end, said rolling means being mounted at said free end. 8. The device for towing, according to claim 1, wherein said means for sliding said skid between said first position and said second position comprises: means for mounting said guiding part on said base; andmeans for sliding said guided part on said guiding part. 9. The device for towing, according to claim 8, wherein said means for sliding said guided part on said guiding part corresponds to groove-rib engagement between said guiding part and said guided part. 10. The device for towing, according to claim 1, further comprising: means for preventing said guided part of said skid from separating from said base. 11. The device for towing, according to claim 10, wherein said means for sliding said skid between said first position and said second position is comprised of said means preventing said guided part of said skid from separating from said base. 12. An assembly, comprising: a board for board sports; anda device, according to claim 1, said device being attached to said board.
