         4 . The binding device according to  claim 3 , wherein the locking element comprises a locking finger able to collaborate with the structured element, the locking finger and the bearing surface of the locking element being arranged one on each side of the second axis. 
     
     
         5 . The binding device according to  claim 1 , wherein the binding device comprises a return means tending to move the locking element towards the locked position. 
     
     
         6 . The binding device according to  claim 5 , wherein the retaining means comprises an elastic blade, the return means being formed by a portion of the elastic blade. 
     
     
         7 . The binding device according to  claim 1 , wherein the operating element comprises at least one cam, rotation of the operating element about the first axis causing the cam to bear against the bearing surface of the locking element to tend to move the locking element towards the unlocked position. 
     
     
         8 . The binding device according to  claim 1 , wherein the operating element comprises a plurality of cams intended to bear against the bearing surface of the locking element, the locking element being in the unlocked position when the bearing surface is bearing against one cam from among the plurality of cams, the locking element being in the locked position when the bearing surface is bearing against the operating element between two adjacent cams from among the plurality of cams. 
     
     
         9 . The binding device according to  claim 1 , wherein the binding device comprises a mechanical transmission means between the operating element and a support intended to be mounted securely on the gliding board or between the operating element and a securing element able to be held securely on the structured element, the transmission means being configured so that:
 turning the operating element in a first direction of rotation causes the retaining means to move in a first direction.   
     
     
         10 . The binding device according to  claim 9 , wherein the transmission means comprises a cable, the cable being intended to be at least partially wound around the operating element when the operating element pivots about the first axis. 
     
     
         11 . The binding device according to  claim 9 , wherein the binding device comprises a pulley, the support being positioned between the operating element and the pulley, the transmission means comprising a first strand and a second strand, the first strand directly connecting the support to the operating element, the second strand connecting the support to the operating element via the pulley. 
     
     
         12 . The binding device according to  claim 9 , wherein the binding device comprises a tension adjusting means for adjusting the tension in the cable. 
     
     
         13 . The binding device according to  claim 1 , wherein the operating element is also mobile in translation parallel to the first axis between the first position and the second position. 
     
     
         14 . The binding device according to  claim 13 , wherein the operating element is locked against rotation when the operating element is in the first position. 
     
     
         15 . A gliding equipment comprising:
 a gliding board, and   the binding device according to  claim 1 .   
     
     
         16 . The gliding equipment according to  claim 15 , wherein the gliding board is a cross-country ski.
