A fluid coupling (10) includes various features. One feature is a disconnect tool (44) that may expand a lock ring (22) from engagement with a lock shoulder (40) to permit the male half (14) and female half (12) to be separated. Another feature is to utilize geometry and structure whereby a leak would occur to indicate the condition of wear within the coupling while the coupling halves (12, 14) remain mechanically coupled. A further feature is to provide connection verification structure to assure that a complete connection of the male end female halves (12, 14) has been made. A still further feature is to provide an anti-rotational sleeve (76) which would selectively prevent and permit relative rotation between the male half (14) and the female half (12).
