摘要

Improved conduit hose, characterized by being constituted by a series of spirals or rings, of a helically wound strip, connected correlatively to each other at their ends, each end having a spiral or ring at one of its ends, a peripheral flange bent straight towards the outside of the ring while the other end has a curved bend that determines a peripheral channel of half-open section towards the interior of the ring; all this in such a way that the channels of the rings are assembled with snap-in pressure on the corresponding circular tabs in order to achieve the unión of the rings and the consequent continuous shaping of the tube.
