The invention relates to a flexible tubular conduit having at least one tubular layer constituted by at least one molded strip of a cross section substantially in the form of an elongated S, wound helically and having a cross section formed of a first and of a second principal cylindrical coaxial spans joined together by an inclined central portion, each of the first and second principal cylindrical spans being united by a first convex radial portion to a first secondary cylindrical span and by a second convex radial portion to a second secondary span. The second secondary span comprises a section connecting to the second convex radial portion (9), an end section (12) and a like intermediate section (13) whose concavity is turned away from the second principal span (6), and the second secondary span (12, 13) is arranged such that, when the strip is in the wound state, the connecting section is thrusting against the first principal span (5') of an adjacent spiral, and the end section (12) applies itself to the said first principal span (5')
