ABSTRACT:
There is disclosed a wellhead connector for connecting first and second tubular wellhead members in end-to-end relation, wherein locking segments are carried by a ring about the first member for movement between an outer position, to permit the ring to be moved over an outer surface of the second member, to an inner position in which locking shoulders on the inner ends of the locking segments slidably engage a locking shoulder about the outer surface of the second member to urge the ends of the members into tight engagement. The locking segments are moved to their inner positions by means of wedges guidably movable in the ring outwardly of the locking segments and having surfaces slidable over surfaces on the outer ends of the segments as the wedges are moved toward one another, and are moved to their outer positions, as the wedges move away from one another, by means of coil springs acting between the body and locking segments.
