ABSTRACT:
A tubing joint having a long life span, in which stress concentration can be avoided even if external force from the tube repeatedly works on the ring claw. In the tubing joint of the present invention, the ring claw is formed into a zigzag shape with outer notch sections and inner notch sections. The ring claw has a plurality of outer ring sections, a plurality of inner ring sections, each of which is provided between adjacent outer ring sections, and a plurality of connecting sections, each of which connects an end of the inner ring section with an end of the outer ring section. The outer notch sections are substantially formed into a U-shape, and inner edges of adjacent connecting sections, which mutually face and form each U-shaped outer notch section, are arranged parallel and substantially perpendicular to the outer edge of the ring claw.
