The pivoting and rigid "FRONT" end-piece for a sailboard wishbone is characterised by the assembly of : 1) a bent aluminium tube 3 on which a ring 2 is fixed, 2) two symmetrical plastic parts in which the tube has been engaged so as to trap the ring, which allows a pivoting from the top downwards and a locking in the transverse direction, 3) a strap or metal collar enabling the end-piece to be fixed to the mast. <IMAGE>
