Abstract
An O-ring is disposed on a front end surface of an abutted collar to prevent a fluid from leaking out of a flow passage when a socket and a plug of a tube joint is coupled to one another. A check valve of each of the socket and the plug, which prevents an outflow of the fluid when the socket and the plug are disengaged from each other, comprises the cylindrical collar (plug body) and a valve element. The valve element is disposed toward an inner diameter of the collar. The valve element has an O-ring disposed on the outer circumference of a columnar section coaxial with the collar.
