Abstract:
A connector for connecting two tubular members, comprising:a pin adapted to be connected to one of the tubular members and having an external annular engagement surface; a box adapted to be connected to the other of the tubular members and having an internal annular engagement surface that receives the pin engagement surface in stabbing engagement; a split lock ring mounted to one of the engagement surfaces for engaging a grooved profile in the other of the engagement surfaces to lock the tubular members together as the pin and box are stabbed together; a wedge shoulder on the pin; a reacting surface on the box and spaced axially from the wedge shoulder relative to an axis of the connector, the wedge shoulder and the reacting surface being at different angles relative to the axis, defining a wedge-shaped space between them when viewed in cross-section; and a wedge member in the wedge-shaped space, having one surface in sliding engagement with the wedge shoulder and another surface in sliding engagement with the reacting surface, the wedge member being radially moveable after the lock ring has engaged the profile to a wedging position wedged between the wedge shoulder and the reacting surface of the box.
