ABSTRACT Safety device for liquefied gas bottle valves provided with quick-coupling connector for use, said device being characterized in that it is positively controlled and activated by the same control knob as the valve, the arrangement being such that the quick-coupling connector can be disconnected only when the valve is completely closed, and vice versa the valve can be opened only when the quick-coupling connector is inserted perfectly, all of which can be effected by a single fixed-amplitude rotation of nearly 360° of the knob, and said rotation causes synchronously - thanks to suitable incorporated means - both the activation of the internal dispensing valve member and the locking of the quick-coupling connector. - 12 -
