The improvements are applicable to those tubular bodies made from flexible material 2 which are to constitute linking elements in installations for conveying fluids, having, as novel aspect, the fact that an intermediate portion 1 of this tubular body 2 has a helical corrugation in whose troughs are respective helical wires 3 constituting a reinforcement of the actual tubular body, maintaining the latter's flexibility and preventing its obstruction even if they are folded or bent owing to installation requirements. The ends of the external wire 3 join together a number of turns which are held by one or a number of plates 4 which are folded on themselves in order to retain these end turns, which plates 4 are housed between the actual wire and the outer lateral surface of the tubular body 2. <IMAGE>
