<p>A breakaway hose coupling includes axially separable housing sections maintained in coupled relationship with each other by a frangible coupling pin or set screw. Each housing section includes a valve controlled flow passage in which a spring biassed valve closes the flow passage when the housing sections are separated. Valve stems on the respective valves moves into axial abutment with each other as the housing sections are coupled to mutually hold the respective valves open when the housing sections are coupled.</p>
