Abstract
A reconnectable frangible coupling wherein at least one coupling part includes an operating valve and a safety valve. The operating valve utilizes the relative axial movement of the coupling parts during coupling and uncoupling to open and close, respectively, and the spring biased safety valve is engaged and retained in an open position by a valve retainer interposed between the valves. Frangible portions maintain the valve retainer in engagement with the safety valve and upon the coupling being subjected to severe impact, such as an aircraft crash, the frangible portions fracture permitting the valve retainer to disengage from the safety valve allowing the safety valve to close.
