The valve has an outlet safety channel (20) closed by a burstable diaphragm (26) wedged between the body (10) of the valve and a plug (24) fitted detachably in the body (10) of the valve, the said plug (24) comprising an axial passage (28) in communication with the outside and filled with a fusible material (32) up to where it comes into contact with the diaphragm (26). A rubber seal (30) resistant to temperatures above the melting point of the fusible material obstructs the axial passage (28) towards the outside.
