<p>The snap-hook device comprises a hook (1) closed by means of a latch held against a stop (1a) by a spring (6). The latch consists of two parts, a lever (2) and a bridge-piece (3) hinged in relation to one another on an axis (4). Another stop (2a) prevents them from pivoting in relation to one another and a spring (5) exerts torque between these two parts of the latch. The snap-hook is opened for hooking-on by the rotation of the latch towards the inside of the hook, against the force of the spring (6), and opened for release by the rotation of the lever of the latch towards the exterior of the hook, against the force of the spring (5).</p> |
