Abstract

When inserting pipe line tubes down drill holes, it is an advantage when the joints between the tube sections are flexible to allow correction of axial alignment. This is achieved by using a coupling ring with a spherical outside diameter. One tube end is provided with a sleeve which has an internal spherical seat for the coupling ring. The end of the other tube which has an external groove fits inside the coupling ring. It is held there by retainer blocks which are inserted radially through slots in the coupling ring. The blocks which are held in position by springs engage the external groove on the tube end thus retaining it in position.
