Coupling device for smoke conducting pipes, characterized essentially by providing each of the sections of pipe constituting the pipeline of a cylindrical sleeve that is internally coupled to said section by spot welding, and protrudes through the mouth a extension sufficient to allow telescopic coupling of another section of the same diameter as the first, joining their ends to end, with the particularity that the extension of the sleeve that projects to receive the other section is provided with forming axial slits of a continuous undulation, in profile, and with slight reduction of the original diameter of the sleeve.
