Device making it possible to fasten an Alpine ski boot 17 onto an Alpine ski safety binding 7, 8 on a snowboard, so as to reduce the risk of injury to snowboarders. The system makes it possible to use ski bindings 7, 8 which are fastened in the direction of the length of the snowboard, while retaining the position of the feet across this same snowboard. The system consists in using two plates, each in the form of a cross, called adaptors 21, the boots 17 being fastened onto the adaptors 21 across the snowboard by virtue of stirrup pieces (clevises) 11, and the adaptors 21 engaging in the bindings 7, 8 via two ends. The system is accompanied by two cables 13 equipped with hooks 25 which can be adjusted in terms of length and are mounted on plates equipped with levers 28 so as to stretch the cables 13. The feet thus connected are entrained mutually at the time of a fall and disconnect when the cables are no longer under tension via ejection of the hooks. Wedges 1, 2, 3 are fastened at the centre and under the ends of the adaptors so that there is no play between the adaptors and the snowboard. <IMAGE>
