A nozzle coupling extends about said flow nozzle for threadingly securing to the flow nozzle to the nipple. The nozzle coupling and the nipple have acme threads which are secured together, with a seal element extending between the nipple and the flow nozzle. A locking collar slidably disposed on said nozzle coupling, for moving from a retracted position disposed aside of the hexagonal-shaped section of the nipple to an extended position disposed adjacent to the hexagonal-shaped section and non-rotatably securing the locking collar to the nipple. The locking collar is non-rotatably secured to the nozzle coupling in the extended position, and non-rotatably secures the nozzle coupling to the nipple when in the extended position.
