A push-pull type fluid coupling having interfitting male and female bodies. The female body carries radially movable ball detents to lock the male body in position, the detents being held inwardly by a rigidly mounted sleeve which supports the female body for relative axial movement. Both bodies have spring biased fluid retaining valves which are opened when the bodies interfit but close when they are disconnected. Two axially disposed springs surround the female body member and coact with the sleeve to resist movement of the body members in one direction, thus providing one level of required uncoupling force while only one of the springs is operative to resist movement of the body members in the other direction, thus providing a reduced force requirement for coupling.
