Abstract
A connection for a tube is formed by placing a coiled spring around an end of a tube and inserting a barbed tubular portion from a connection into the tube. The connection forces the tube to expand applying pressure against the coil spring and forcing it to expand and exert radial pressure against the tube towards the inserted tubular portion.
