Permanent safety device for preventing the accidental firing of a weapon whose firing mechanism comprises a trigger, a hammer, a loaded spring which exerts a force along a given line of action on said hammer, retention means which hold the hammer in opposition to said spring and, inserted between the trigger and said hammer retention means, a lever which disengages these latter at the time of firing as a result of the trigger being pulled. The abovementioned firing mechanism includes a stop piece which can be moved between an interference position in which it interferes with the action of said spring on the hammer and a position in which it does not interfere with said action, and vice versa, and a mechanism, connected to the trigger, which is designed to move said stop piece out of said interference position only if the trigger is pulled.
