Beschreibung
Zusammenfassung:	A connector for connecting sections of drilling riser pipe wherein a first riser contains a pin assembly (27) with an external first grooved profile (33) and a second riser contains a housing assembly (23). An internal split pivoting latch segment assembly (29) carried by the housing assembly contains a second grooved profile (31) adapted to mate to the first grooved profile and a split actuation ring (41) movably carried by the housing assembly forces the second grooved profile of the latch segment assembly into engagement with the first grooved profile of the pin assembly. A plurality of retraction links (45) engage an upper edge of the latch segment assembly to disengage the second grooved profile of the latch segment assembly from the first grooved profile of the pin assembly if the risers are to be disconnected.
