Abstract

The invention relates to the fitting of a security lever to avoid premature unlocking of rapid locking and unlocking devices of the latch and trigger/button type used more particularly on aircraft. The security lever 9 is integrated with the latch 2 and, when the device is in the locked position, is housed in the T-shaped groove in the trigger/button 3, thus solidly attaching the latch 2 and the trigger/button 3, preventing unlocking as long as the lever 9 remains in the closed (down) position. Unlocking is performed by raising the lever 9, which must tilt to a position of approximately 120 DEG with respect to the base of the catch 2 (required pressure: 500 bar). Pressing on the trigger/button 3 then allows unlocking. The security lever 9 is held in position by the action of the spring 4.
