<p>This invention relates to a flexible pipe (2) for a pipe construction extending through a roof. This flexible pipe is an accordion-like pipe, made of rubber, having a cylindrical upper end (2a) intended to be slipped onto the lower end of a pipe part (3) extending above the roof, and a cylindrical lower part (2b) intended, in turn, to be slipped onto the upper end of a lower pipe part (1) which ends underneath the roof, said cylindrical parts (2a, 2b) being attachable to the ends of said pipe parts (3, 1) by means of host clamps (4a, 4b). The invention is characterized in that inside the cylindrical lower part (2b) of the flexible pipe (2) a cylindrical collar (2c) has been arranged having an outer diameter corresponding to the inner diameter of the pipe part (1) to be connected to the lower end of the flexible pipe (2) and said collar being joined in its upper end tightly to the inner surface of the cylindrical lower end (2b) so that between the cylindrical collar (2c) and the cylindrical part (2b) surrounding the collar a receiving space is formed to receive the upper end of the pipe part (1) to be connected thereto.</p> |
