Abstract

A connection assembly, for connecting a tool to a tube, having a top sub-assembly that can be passed over a tube, a gripper to grip the outside of a tube when compressed, a sealing ring, adapted to seal against the end face of the tube, a bottom sub-assembly having an abutment face for the sealing ring; and where the two sub-assemblies can be held together to trap the gripper between them. A method for joining a connection assembly to the end of a tube by locating a top sub-assembly around the tube; abutting a sealing ring between the end face of the tube and a bottom sub-assembly; locating a gripper around the tube between the two sub-assemblies and applying a compressive load to them to effect a seal between the tube and the bottom sub-assembly, and to cause the gripper to grip the outer surface of the tube.
