A hollow tube connector is used to make detachable fluid-tight connection of two connector parts. The tube connector includes a first connector part, wherein a first of its two axial ends is configured to connect to a pipeline on a vessel, and a second connector part, wherein a first of its two axial ends is configured to connect to a pipeline on an STP-buoy. The coupling surfaces of the second axial ends include a non-crossing groove circumferentially around the contact surfaces, and a groove located on one of the contact surfaces and having a mirror-imaged groove located on the other contact surface. The two opposite grooves form an encompassing cavity upon contact of the contact surfaces. At least one of the contact surfaces is tapered relative to an axis perpendicularly to a center axis and forms a pre-tensioned abutment which increases the resistance to relative motions between the contact surfaces. |
