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. The invention also proves 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 said gripper to grip the outer surface of the tube. The two subassemblies are then held together, trapping the gripper between them. The compressive load may then be released. |
