Abstract
The safety lock comprises a control member which prevents an untimely actuation of the jettisoning device by inserting a locking member on the path of a movable release member of this device. Simultaneously the safety lock releases braking members in order to allow nuts to rotate for ensuring the raising of the hooks to which the load is suspended.
