Abstract
An apparatus for locking together male and female coupling members for use in undersea production and drilling applications is disclosed. A lock pin engages a circumferential groove around the body of the female coupling member. The lock pin may be released to allow partial separation of the male and female coupling members while the valves of each coupling member are closed, allowing the coupling members to remain connected subsea while the flow of hydraulic fluid is shut off.
