PROBLEM TO BE SOLVED: To provide a duct joint having a wider application range, easy to manufacture with fewer components, and stably connecting a duct in a bent condition. SOLUTION: A first square cylinder body 11 is constituted by a first half square cylinder body 21 and a second half square cylinder body 22. To the end of the first square cylinder body 11 via a turning mechanism 12, a second square cylinder body 13 is turnably connected which is constituted by a third half square cylinder body 25 and a fourth half square cylinder body 26. On the bottom plate 21a of the first half square cylinder body 21 and in the bottom plate 25a of the third half square cylinder body 25, a thin portion 21c and a through-hole 25c are formed, respectively, through which a screw nail can pass to fix them to a wall face.
