A tubing joint (10) includes a ring claw (112) formed into a zigzag shape with alternating outer notch sections (113) and inner notch sections (115), said ring claw (112) including a plurality of outer ring sections (117), a plurality of inner ring sections (119) each of which is provided between adjacent outer ring sections (117), and a plurality of connecting sections (120) each of which connects an end of the inner ring section (119) with an end of the outer ring section (117). The outer notch sections (113) are of substantially U-shape, and inner edges (120a) of adjacent connecting sections (120), which mutually face and form each U-shaped outer notch section (113), are arranged parallel and substantially perpendicular to the outer edge (A) of the ring claw (112). <IMAGE> |
