Claims

[Scope of Claim for Utility Model Registration] (1) A recess that forms a through-hole with an axial cross section that is hourglass-shaped by opposing the mutually opposing connecting ears of the two-split metal fitting that is attached to the outer periphery of the socket. A groove is formed, and an arm extending toward the receptacle is inserted into the outer insertion hole in a non-removable manner, and at the axial end of the arm, a T-shaped branch arm is formed in a direction perpendicular to the axis. Hooking pawls are integrally protruded and are folded back parallel to the axis at both ends of the branch arm, while at the rear end of the enlarged diameter portion of the socket, bifurcated metal fittings are opposed to each other. The ear pieces are arranged to face each other, and the shaft of the arm is inserted between the ear pieces, and the T-shaped branched arm at the tip of the arm is between the hooking claw body at the tip of the arm and the hooking claw body at the tip of the arm. A tube detachment prevention device characterized by being attached by pinching an ear piece. (2) Concave grooves are formed in the mutually opposing connecting ears of the two-split metal fitting attached to the outer periphery of the socket, and the grooves are formed to form a through hole with an axial cross section that is hourglass-shaped. An arm extending toward the socket is inserted into the hole in a non-removable manner, and a T-shaped branch arm is integrally provided at the axial end of the arm in a direction perpendicular to the axis. At the rear end of the enlarged diameter part of the mouth, a bifurcated metal fitting having ears protruding in the radial direction at the end is arranged with the ends intersecting in a staggered manner and the back surfaces of the ears facing each other, A tube detachment prevention device characterized in that the T-shaped portion at the tip of the arm is inserted between the ear pieces.
