A ball detent fluid coupling for gas fuel for appliances and the like equipment is characterized by push-to-connect and pull-to-disconnect features, a heat responsive breakaway feature, and a ball retaining sleeve that is retractable by hand for joining and for separating the socket and plug. The sleeve has a shoulder projecting radially inwardly with an inclined surface for engaging the balls. The spring for the sleeve is urged against the shoulder by a fusible stop ring that is matingly mounted on an inclined shoulder on the socket. The stop ring fuses at a predetermined temperature, the spring is released, and the sleeve releases the ball detents from engagement with the plug. A valve in the fluid flow passageway urges the plug out of coaxial coupled relation and stops the flow of fuel when the plug and socket are released from coaxial coupled relation.
