Abstract: The present invention relates to a process and a device for dividing a tubular flagpole. This is achieved by introducing into the flagpole an elongated body, which over at least part of its length has a geometric shape, which in concert with a complementary geometric shape inside the flagpole ensures that the flagpole can be cut and assembled in a way that guarantees the rectilinear continuity of the flagpole. The complementary geometric shape is formed in that, after the body is introduced into the flagpole, a filling material is injected so that the space between the flagpole and the elongated body is filled. The flagpole is then cut around the elongated body down to the outer surface of the body so that the geometric shape allows the flagpole to be divided into two sections at the cutting side, the body remaining fixed to one of the sections.
