Abstract

There is disclosed a subsea wellhead connector comprised of a lower tubular member mounted on the upper end of a lower wellhead member, and an upper tubular member suspended from an upper wellhead member for lowering into end-to-end connection with the lower tubular member. Locking teeth are formed about the ends of the tubular members, and circumferentially spaced locking segments are carried by the upper tubular member for movement radially into or out of locking engagement with the grooves about the upper and lower tubular members. The locking segments are moved inwardly to locking position by means of a cam ring which surrounds them, and are withdrawn from locking position by spreader dogs carried by the cam ring and extending between the ends of adjacent locking segments.
