A device for fixing the wish-bone of a sail-board to the mast of this sail-board in a fast and easy manner. The device comprises a U-shaped element intended to be connected to the mast, this element having two sleeve-shaped ends in which are inserted both arms of the wish-bone. A column-shaped, mast-engaging body is provided to connect the U-shaped element to the mast. This body has a bearing surface against which the mast may engage. A lever-operated, hook-clamping system is mounted on both sides of the bearing surface of the body to fix this body to the mast after the mast has been positioned against the bearing surface, such a fixation providing the requested connecting of the U-shaped element and wish-bone attached thereto to the mast. This device is particularly interesting in that it considerably simplifies the relatively delicate installation of the wish-bone onto the mast of a sail-board.

A device for fixing the wish-bone of a sail-board to the mast of sail-board, said device comprising: a U-shaped element intended to be connected to the mast, said U-shaped element having two sleeve-shaped ends into which are inserted both arms of the wish-bone; a column-shaped, mast engaging body provided with a bearing surface which may be positioned onto the mast said mast engaging body being rigidly connected to the U-shaped element and forming therewith one single piece fixable to the mast; and a lever-operated, hook clamping system rigidly mounted on said mast engaging body to fix it in a fast and easy manner to the mast after said mast has been positioned onto the bearing surface; said fixation of the mast engaging body resulting in a fast and easy fixation of the U-shaped element and of the wish-bone attached thereto to the mast, wherein said lever-operated, hook-clamping system comprises: a lever support fixed to the mast engaging body close to one side of the bearing surface of said body; a lever mounted about a pivot on this support, said pivot having an axis substantially parallel to the mast when the same engages the bearing surface; a strap having one end free and the other end mounted about a pivot onto the lever at a short distance from the pivot of this lever, the pivot of said strap being parallel to the one of said lever, said strap having a length sufficient to pass around the mast when the same engages the bearing surface, and comprising a plurality of teeth over a portion of its length close to its free end; and a hook-clamping device connected to the mast engaging body close to the other side of the bearing surface for receiving and retaining the free end of the strap when this strap is passed around the mast with said mast engaged against the bearing surface, said hook-clamping device comprising a pawl urged against the teeth of the strap to engage the same; said lever support and hook-clamping device being mounted at the ends of a stirrup mounted onto the mast engaging body so as to extend all around the surface of said body opposite to the bearing surface; whereby the rigid body can be rigidly fixed onto the mast by merely tensioning the strap with the lever when this strap is engaged in the hook clamping device, said lever being positioned so as to remain in a dead position after the tension is exerted.
