A method of locking tubular components in end to end relation. A first tubular body is provided having a tongue with an outwardly facing groove protruding past one end along an interior surface that has a keyway. A second tubular body is provided having a tongue with an inwardly facing groove protruding past one end along an exterior surface. A split ring is positioned in the grooves to connect the bodies. The split ring has a tapered outer surface to permit removal by an axial force. A tubular insert carries a locking key which engages the axial keyway. When the tubular insert is fully inserted into the first tubular body, the key underlies the split ring and prevents the split ring from having sufficient clearance to be withdrawn.
