Zusammenfassung:	A pipe connector especially useful in tying back to a subsea wellhead with a marine riser. The connector comprises a body or sub, a collar surrounding the sub and carrying anti-rotation keys and a lock ring, and an actuator nut surrounding and threaded to the sub. The anti-rotation keys prevent rotation of the collar and the nut with respect to the receptacle into which the connector is run, and rotation of the sub with respect to the collar and nut locks the connector into the receptacle and establishes a metal-to-metal seal therewith.
