ABSTRACT:
A constrictor ring and tube joint formed thereby in which the constrictor ring is provided with a tapered bore and which is also tapered externally in such a manner that the end having the smaller internal diameter also has the greater external diameter. The constrictor ring is internally dimensioned to be partially received on a collar or coupling connecting the ends of two tubes placed in abutment or the enlarged or bell end of a tube which receives the plain end of a mating tube and then is forced over the collar or bell end to cause local annular compression of the collar or bell end sufficiently to cause corresponding annular compression of the tube within and produce a high strength fluid tight tube joint.
