A pipe connector with helically threaded (49, 57) frustoconical pin (10) and box (30) surfaces. The connector is axially (78) snapped together, but is rotated for disengagement. Centralizing surfaces (150, 152) on each thread form abut opposing crests (62, 54) to maintain concentrically, thereby detering disengagement under bending moments.

Pipe connector

An anchor connector incorporating a flexible joint (16) for securing the tension legs (14) of a tensioned leg platform. A latch dog head (34) engages a first recess (26) on the fixed member (22) of the flexible joint and a template recess (30) to prevent disconnection when the dog heads (34) and latch carrier (40) are in a lower position. With the latch carrier (40) in an upper position the latch dog heads (34) fit within a second recess (44) in the fixed member with the dog heads claring shoulder (32) of template recess (30), whereby the connector may be released.
