CONNECTOR FOR PIPING

PROBLEM TO BE SOLVED: To prevent drawing of a joining part by providing with a fixed split ring which is fixed to a spigot side of a pipe body, a restricted split ring which abuttingly locked with the step part backward a receiving port by loosely fitted to the receiving side of the pipe body, and a connecting member for connecting the fixed split ring and the restricted split ring to each other within a prescribed expanding/contracting range. SOLUTION: A connecting tool of a piping for fitting and joining a pipe body 1 provided with a receiving port 1a and a pipe body 2 provided with a spigot 2a inserted into the receiving port 1a in/with each other through a seal material 3, is provided with a fixed split ring 4, a restricted split ring 5, and a connecting member 6. The fixed split ring 4 and the restricted split ring 5 are formed as annular bodies installed on the pipe bodies 1, 2 respectively, and they are divided into two parts of a female and a male 4A, 4B and a female and a male 5A, 5B. The connecting member 6 is formed as a rod shaped body for connecting the split rings 4, 5 to each other, an installing hole 61 installed in a clearance between connecting pieces 45, 45 of the fixed split ring 4 through a bolt 7 is arranged on one end side of the connecting member 6, and a sliding hole 62 installed in a clearance between joining pieces 56, 56 of the restricted split ring 5 through the bolt 7 is arranged on the other end side of the connecting member 6.
