ABSTRACT:
A ratcheting connector for providing a radial connection between two concentric tubular members, with one of the members having a recess in which a split latching ring is mounted with coarse threaded engagement between said split latching ring and said one member and fine threads on the side of said split latching ring facing the other member which has mating fine threads with a shape which cams said split latching ring into its recess as the threads move past each other in the direction of installation. Setting of the connector is accomplished after full engagement of the fine threads by rotation of the central tubular member less than a full revolution.
