A water stop hose connector having a male member and a female member having an open end and an O-ring dimensioned to receive an inner end of the male member, and detent balls and groove to retain the male and female members together, a quick connect, axially movable cylindrical collar movable over the detent balls to lock them in the detent groove and movable away from the detent balls to release them from the detent groove, a spring biasing the collar over the detent balls, a valve body retained in the female member and having a head, a stem, and a stop shoulder on the stem, and movable between first and second positions, the stem having flow openings, an O-ring around the valve body head, the valve body openings in the second position being in flow communication with the female member and in the first position being out of flow communication with the female member to prevent flow, the valve body being engaged by the male member axially inner end face when the male and female members are coupled, causing the valve body to move to the second position, and movable to the first position by water pressure when the male and female members are uncoupled.
