To provide a flexible tube traction tool, with which a flexible tube such as a polyethylene resin tube or the like can be easily inserted with a low tractive resistance into a tubing such as a gas tube, a water tube or the like.
This traction tool is equipped with a spherical body part 7, which can be pulled with a traction rope 4, a spherical body 6, the outer diameter of which is smaller than the inner diameter of a piping 1 by the amount passable through the piping, a connecting part 8 connectable with the tip part of a flexible pipe 5 and a connecting rope 9, which connects the central part 7a of the rear surface of the spherical body part 7 with the central part 8a of the tip surface of the connecting part 8. The length of the connecting rope 9 is made so as not to contact with the inner wall 3 of the pipe of the piping 1 when the connecting rope 9 under tension passes through the bent part 2 of the piping 1. Further preferably, the spherical body part 7 is made by connecting a plurality of spherical bodies 6 in tandem through a flexible or bendable connecting member.
