ABSTRACT:
A tube connector comprising a first member and a second member, each member being made from a sheet metal stamping. Each member includes an annular portion, a tubular barrel, and plural legs. The tubular barrel extends from an inner periphery of the annular portion. The legs extend outwardly from the annular portion and are adapted to flex axially so as to facilitate insertion of such member into the tube through one end of the tube. The legs have sharp edges tending to dig aggressively into an inner wall of the tube so as to resist withdrawal and rotation of such member. The tubular barrel of the first member fits within and extends through the tubular barrel of the second member and is crimped at one end so as to secure the tubular barrel of the second member bears at one end agains the annular portion of the first member. The tubular barrel of the first member is internally threaded and consequently deformed so as to fit tightly within the tubular barrel of the second member.
