A quick disconnect coupling is disclosed for releasably interconnecting first and second fluid flow members each having a fluid opening. The coupling includes a base member having a bottom surface, an annular attachment collar defining an inner fluid port axially through the base member and including an outer cylindrical side wall, and an annular shoulder surrounding the attachment collar. A mechanism is provided for mounting the base member bottom surface to the first fluid flow member in order to align the fluid port with the fluid opening of the first fluid flow member. A connecting plate is further provided having a top and bottom surface and a central aperture defining an inner cylindrical sleeve sized for journaling about the collar side wall for limited rotation thereabout. The connecting plate also includes an inner annular shoulder disposed along the bottom surface radially outwardly of the sleeve, the connecting plate upper surface being adapted for connection to the second fluid flow member. A spring device is positioned on the base member annular shoulder and is adapted for resilient compression between the annular shoulders when the connecting plate is journaled about the attachment collar. Finally, a locking mechanism releasably locks the connecting plate to the base member and includes art interacting tongue and groove assembly adapted interengagement upon rotation of the plate about the collar with the spring means biasing the plate axially away from the base member to exert an axial force against the tongue and groove assembly.
