Claims

[Claims for Utility Model Registration] 1. A pipe detachment prevention fitting that is divided into a plurality of pieces and is tightened on the outer peripheral surface of a pipe at a joint portion where two pipes are connected in a flexible and expandable manner. At the tip of the flange portion formed at both ends of each split piece metal fitting, a protruding piece that protrudes toward the flange portion side of the other adjacent split piece metal fitting is formed, and a T is formed on one side of each opposing flange portion. A bolt insertion hole is formed on the other side to form a long hole into which the head of the T-bolt can be inserted and a seating part for the head, and between the opposing flanges and both protruding pieces, one tube and the other tube are formed. 1. A pipe detachment prevention device for a pipe joint, characterized by forming an insertion space for a connecting rod for connecting the pipes. 2. The pipe separation prevention device for a pipe joint according to claim 1, wherein the pipe separation prevention fitting is attached to at least one pipe in the pipe joint portion.
