The disclosure concerns the field of charges releasable from an aircraft to which they are fixed and, particularly, the keel beam safety device that prevents the activation of the charge when it is hooked on beneath the aircraft. A mechanical safety device for the keel beam consists in using the driving force of a sensor that is rotationally free in a support, by means of cable going into said sensor, one end of which is fixed to an aircraft and the other end to means for activating a fuse for the firing of a charge. To this cable, there is fixed a ball which, when a tensile force is exerted on the cable, comes into contact with the sensor and draws it, after the unlocking of the holding system, through a sufficient tensile force exerted on the cable, into contact with the aircraft when the charge is fixed beneath the aircraft, thus preventing any additional movement of the cable. When the charge is released, the cable can be pulled freely and enables the charge to be activated. The disclosure can be applied to bombs where the firing fuse is screwed in along the axis of the bomb, and to all bombs of the MK type.
