Abstract: A device for manual or automatic opening of an aircraft safety equipment box includes a pin fixed to the box door, a pivotable hook engageable with the pin, and a resilient return assembly associated with the hook. The return assembly has a main spring urging the hook to a disengaged position and a locking lever pivoted about the same axis as the hook. In its locked position the lever abuts and holds the same part of the main spring as holds the hook in its engaged position. In the release position the lever frees the main spring to drive the hook to disengage it from the pin. The return assembly further has a secondary spring for returning the lever to its release position and the hook to its engaged position. The return assembly includes a release plate locking the lever in its locked position. Displacement of the plate causes the hook to disengage from the pin.
