The clasp includes a central element 1 comprising first 2 and second 3 branches fastened to each other by first 4 and second 5 fastening means, a free space 6 being provided between the branches. A first 7 and a second 8 arm are articulated, each via one of the ends thereof, about the said fastening means. In the closed position, the arms are partially included in the thickness of the central element.
<??>In order to block the clasp in the closed position, each arm 7, 8 is provided with a snout 13, 14 capable of coupling onto a rod 15, 16 joining the branches of the central element. These rods are held axially in blind holes pierced in the thickness of the branches and are capable of pivoting on themselves when the snouts couple onto the rods.
<??>A clasp is thus produced, whose blocking elements wear very little and, above all, are very thin.
