ABSTRACT:
The present invention relates to a L.P.G. hose breakaway coupling which is adapted to separate at a pre-determined force. The coupling comprises two internal valves located on each side of the coupling which automatically seal each half of the coupling upon disconnection. The coupling is lightweight in construction when compared to existing devices and is simple in operation as well as being robust in construction. The two halves of the coupling are connected by releasing a bias member and directly coupling the two halves of the coupling together and then resetting the bias member to load the release mechanism.
