Binding device for gliding board

A front binding device for holding a boot on a gliding board, comprising:

• a retaining means able to collaborate with a front part of the boot, and
• an adjusting device for adjusting a position of the retaining means relative to the gliding board,
• the adjusting device comprising:
• a structured element comprising a series of reliefs, the structured element being intended to be mounted securely on the gliding board,
• a locking element mobile between a locked position in which the locking element is engaged with the structured element in order to lock the position of the retaining means, and an unlocked position in which the locking element is disengaged from the structured element in order to adjust the position of the retaining means, and
• an operating element supported by the retaining means and intended to be actuated by a user, the operating element being mobile in rotation about a first axis parallel to a vertical axis, the operating element being mobile between at least a first position and a second position, the operating element bearing against a bearing surface of the locking element so that the locking element moves from the locked position to the unlocked position when the operating element is actuated from the first position to the second position.
