Abstract The improved joint of the present invention includes a first tubular member having a central bore, a counter- bore, and an axially extending first rim having an interior land and groove recess therein and internal seal means near the end of said first rim, a second tubular member having a central bore, a counterbore, an axially extending second rim having an outer diameter less than the inner diameter of said first rim on said first tubular member, an external sealing surface near the base of said second rim and an axially facing stop shoulder at the base of said second rim and extending outward from the exterior of said second rim, a sleeve positioned within and spaced slightly inward from said second rim and sealed to the interior of said second rim at a position near the base thereof and at a position near the outer end thereof, and a port extending through said second tubular member providing communication between the exterior of said second tubular member and the space between said sleeve and the interior of said second rim and a fitting secured in the exterior opening of said port for receiving a pressure fluid hose releasably thereon. With this configuration, fluid under pressure applied to said port causes said second rim to be forced outwardly into said land and groove recess to provide a sealing and gripping engagement between the exterior of said second rim and the land and groove recess on the interior of said first rim.
