description An externally actuatable tieback connector for establishing fluid communication and force resisting connection of a conduit to a subsea wellhead having an internal locking geometry. The tieback connector has a body structure that is adapted for landing on a wellhead, with a part thereof extending into the wellhead and carrying a split lock ring. A lock energizing element, moveable relative to the body structure, has a locking position expanding the lock ring into locking and pre-load force transmitting engagement with the internal locking geometry of the wellhead and an unlocking position releasing the tieback connector from the wellhead. One or more drive members extend from the lock energizing element and are exposed externally of the connector body and wellhead for engagement and actuating movement by a lock actuating tool such as a ROV or the like.
