Abstract
A hose with interlocked profile, particularly for automotive exhaust systems. The hose is helically stripwound from at least one single-layer or multi-layer metal strip, pre-formed to the shape of an S, with the edges of adjacent strip windings being interlocked with each other by the legs of the pre-form which have the aspect of the S-shaped hooks, and by folded end rims. The hose has radial embossed recesses which bring adjacent interlocked folded edges partially in direct contact with each other.
