A B S T R A C T O F T H E I N V E N T I O N "PIPE CONNECTION JOINTS" A pipe connection joint comprises two coaxial tubular joint members 1 and 2 which are telescopically engaged, one within the other. The outer member 1 has a bore 3, and the inner member 2 a through bore 4, of the same diameter as that of the pipeline with which the joint is to be used. The inner member 2 is received in a counterbore 5,6 in the outer member 1, being an interference fit therein over an interface region to provide both a seal and a friction lock precluding relative axial separation of the joint members under internal pressure. The joint member 2 incorporates an externally connectible duct 16 which leads to said interface region, whereby fluid under pressure can be introduced to relieve said friction lock.
