Invention herewith described refers to the assembly tool for sewer pipes providing the connection of the pipe (2) wherein there is mounted the pipe (1) so that the pipe (l) is girded with the chain (3A). The chain is secured with a hook (4A), and the rest of the chain (3B) is directed along the pipe (1), and then along the pipe (2) to the hook (7A). Another chain (3C) is by the hook (4B) attached to the chain (3A) and at the other end it is attached to the handle (7) in the section (7A). The subject matter is the basic version with three alternative solutions given in the description.In the basic variant, the tool rests on the pipe (2) face and by pushing the handle forward pulls the chains (3B and 3C) that through the chain (3A) draw in and connect the sewer pipes (1 and 2). In the variant 1, the tool also rests on the pipe (2) face and pulls another pipe through the handle, the hook and the chains.In the second and third variants, the tool is mounted on the smooth part of the pipe and firmly tightened to prevent slippage during the pipe fitting. All versions include a variety of pipe diameters, except the third one which has profiled two-piece rings for all pipe dimensions.
