  • Snap-hook device for attachment to an object such as a ring or mooring buoy, and release thereof, particularly for boats
    Patent number: 6450558
    Abstract: A snap-hook device comprises a hook closed by a latch held against a stop by a spring. The latch consists of two parts, a lever and a bridge-piece hinged in relation to one another on an axis. Another stop prevents them from pivoting in relation to one another and a spring 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, 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.
