ABSTRACT:
The improved remotely actuated collet connector of the present invention is suitable for joining tubular members with similar or different end preparations or profiles and includes a housing to support the connector from a first tubular member, a plurality of collet fingers or segments mounted within the housing and around the exterior of the first tubular member, an actuator ring surrounding the fingers to move the fingers to release or latch position, pressure responsive means for moving the actuator ring, each of the collet fingers having a first engaging surface and an adapter secured to the finger and having a second engaging surface, said first engaging surfaces mating with the end profile of the first tubular member and said second engaging surfaces of said adapters mating with the end profile of the second tubular member so that when the collet fingers are moved to latch position they secure the first and second tubular members together. A seal ring having a configuration to mate with the internal end sealing surface of the first and second tubular members is positioned to seal between the end sealing surfaces of the members when they are secured together.
