Abstract: The preferred and illustrated embodiment is a connector adapted to be joined above a blowout preventer and below the rotary table of a drilling rig. It collects the annular flow of returned drilling mud and directs mud to an incorporated, radially directed connective nipple. It enables the blowout preventer to be adjusted in location relative to the drilling rig and further accommodates a variable level of drilling mud in the annular space. The radial nipple connects with a mud line extending at some radial direction with a slope causing the mud to flow by gravity from the annular space to remote located mud tanks.
