RATCHETING AND THREADED WELL CONNECTOR Abstract of the Disclosure A ratcheting and threaded connector for connecting an upper and lower tubular member which allows an upper member to be connected to a lower member with a ratcheting action and on subsequent rotation causes a threaded spring to move into position to engage shoulders on both the upper and lower members to place them in a rigid and tight relationship. Multiple load bearing shoulders on each of the members coact with load bearing shoulders on the spring to provide a substantially equal balance load distribution and allows the connector spring to have a minimum thickness.
