Abstract
The connector housing is integrally provided with a tube connecting portion on one axial end thereof and a pipe inserting portion on the other axial end thereof. An internal valve is disposed in the connector housing for opening and closing the through-path. The internal valve has a valve seat surface defined on an inner peripheral surface of the tube connecting portion. A valve body includes a closing portion with an abutting surface for abutting with the valve seat surface on an outer peripheral portion of the closing portion, and a compression spring biases the valve body in an axial direction. The valve body is configured to be movable in the axial direction within confines of the tube connecting portion that is provided with an annular stop rib.
