PROBLEM TO BE SOLVED: To provide a positioning device for pipe body capable of easily positioning pipe bodies on a same axis even in a small space. SOLUTION: This positioning device for pipe body comprises an angularly displaceable first arm 28 fitted to a first complete round ring 27 coaxially clamping an existing fixed pipe 21, a second arm 31 fitted to a second complete round ring 30 coaxially clamping a newly-laied pipe 22, and a groove aligning stand 29 connected to the first arm 28 and the second arm 31 at specified anglesθ1 andθ2 and disposed opposedly to the first arm 28 and the second arm. Since the arms 28 and 31 are connected to the groove aligning stand 29, the axes of the complete round rings 27 and 30 can be coaxially disposed. Thus the pipe bodies 21 and 22 clamped by the complete round rings 27 and 30 can be easily disposed coaxially.
