AbstractA lockring tube joint, including an inner and an outer axially overlapping tube member, and a lockring having internally an initial cone frustum zone joined at its smaller end to a cylindrical zone, and a subsequent cone frustum zone joined at its larger end to the cylindrical zone; the tube members being dimensioned to undergo corresponding radial compression in the regions of the cone frustum zones upon assembly of the lockring thereon. Other embodiments of the lockring being provided with additional cone frustum zones and cylindrical zones, and other embodiments of the tube members having localized ribs to provide corresponding localized constriction for increased bonding and sealing engagement between the tube members.
