A tubular hose for transporting fluids in industrial installations and a method for the manufacture thereof. The tubular hose includes an external layer of a polymeric material, preferably silicone, provided with a code, intaglio engraved using a laser on the external surface of the external layer formed by a plurality of grooves arranged according to a pattern of the code. The grooves are at least partially filled with a filler material with a colored polymeric base which produces a visual contrast with the rest of the external surface of the external layer. The code is preferably a two-dimensional code.
