PURPOSE: To provide a synthetic resin coil for preventing the kink of a hollow conduit capable of being mounted at the place where a kink is easy to generate and/or the place where the kink is already generated of the hollow conduit and to prevent and/or protect the kink of the flexible hollow conduit using said coil.
CONSTITUTION: A synthetic resin coil has restoring properties (1) capable of stretching the coil substantially linearily and capable of restoring the coil to a coil shape before stretching when stretching force is released even after the coil is stretched substantially linearily and adhesion winding properties (2) capable of winding the coil around a flexible hollow conduit in a close contact state in a coil form without allowing the same to bite in the conduit when the coil is wound around the hollow conduit in a state stretched substantially linearily.
