Abstract
A wellhead connection including first and second housings with the first housing partly within the second housing to form an annulus. The housings form a seal to a cylindrical inner bore when connected together. The first housing has a circumferential groove formed in its outer periphery. A radially expandable and contractable latch ring formed from latch ring segments is located in the annulus adjacent the circumferential groove. Radial actuators extend through the second housing to the latch ring segments to move the latch ring segments between a contracted position with the latch ring in contact with the circumferential groove, and an expanded position, with the latch ring out of contact with the circumferential groove. The upper and lower housings are adapted to lock the latch ring in the contracted position by applying a downward force on the latch rings, or by tightening the bottom connector to a wellhead member.
