A spring lock nut assembly for coupling a tube to another member such as a valve, manifold, other tube or the like, includes a tail piece which is brazed onto the tube, a spring lock wire and a spring lock nut. The spring lock wire is diamond-shaped in cross-section and has two surfaces received in an internal V-shaped groove in the lock nut. The remaining two surfaces of the lock wire project from the V-shaped groove. One of the surfaces of the lock wire which projects from the groove projects at an angle of about 45° and abuts a 45° shoulder on the tail piece. This abut- ment prevents the spring lock nut from being removed from the tube but allows the spring lock nut to rotate so as to effect a threaded coupling with the other member.
