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first tubular body, the key underlies the split ring and prevents the split ring from having sufficient clearance to be withdrawn.

Méthode de verrouillage de composants tubulaires bout à bout. Une première structure tubulaire est fournie qui est dotée d'une languette et d'une rainure frontale externe qui dépassent sur une extrémité le long d'une surface intérieure dotée d'un trou de serrure. Une seconde structure tubulaire est fournie qui est dotée d'une languette et d'une rainure frontale interne qui dépassent sur une extrémité le long d'une surface extérieure. Une bague à fente est placée dans les rainures pour raccorder les structures. La bague à fente possède une surface extérieure profilée afin de permettre le retrait par une poussée axiale. Un insert tubulaire est doté d'une clé de verrouillage qui active l'entrée de clé axiale. Quand l'insert tubulaire est entièrement inséré dans la première structure tubulaire, la clé est placée à la base de la bague à fente et évite qu'il y ait suffisamment de jeu autour de la bague à fente pour que l'insert puisse être retiré.
