A male coupling member (22) having a front end and a back end and defining a path (32) for the flow of fluid therethrough, the front end of the male coupling member (22) being insertable into the front end of the female coupling member (24). A seal (36) cooperates with an external surface of the male coupling member (22) and an internal surface of the female coupling member (24) for providing a fluid tight seal therebetween. A one piece quick connecting/disconnecting clip member (26) is slidably mounted in a slot (58) of the female coupling member.
