Abstract

Flexible pipeline comprises an elastic hose with an external reinforcing spiral winding, connecting fittings at each end of the elastic hose in the form of a through connecting outlet or inlet fittings, respectively, and one of two identical couplings. The end of the hose is sealed between each connecting pipe and coupling. The coupling is made hollow with an inner spiral groove along the longitudinal symmetry axis of the coupling. The connecting pipe is made with a cylindrical surface pressed into the end of the elastic hose. At the end of the hose, the pipe and the coupling are secured with a retaining ring. The cylindrical surface of connecting pipe is made inclined with conical protrusions. The retaining ring is made split of a spring material, with flat lateral surfaces resting on the walls of the coupling windows and with a cut, the ends of which protrude into the windows made in the coupling wall.
