Automatic safety device for compressed gas containers, characterized in that the gas outlet from the pressurized container to the blocking valve inherent therein, takes place through a device essentially having a transverse chamber to the general direction of gas circulation, a tree, operative provided with a central obturator and pushed by a spring that applies its front end against a spherical body in the matter of low pre-set melting point, so that the gas has normally free passage by said chamber towards the blocking valve, while upon an accidental rise in temperature due to inflammation of the gas in said valve or in its vicinity, or to another external cause, the fusion and consequent inoperation of the said spherical body takes place., in whose eventuality the spring displaces the tree until its shutter is placed against the outlet of the chamber to transversal, determining the automatic interception of the gas passage, in whose action the own pressure of the bottled gas collaborates.
