Abstract

A reinforced flexible hose 1 of elastic material (rubber) has end parts 2 and at least one intermediate portion 3 having cylindrical outer surfaces 2 of outside diameter greater than that of the intermediate parts which have a corrugated outer surface 4. The reinforcement comprises layers or groups of layers of textile material 5 and a helically wound rigid element 6 which extends the length of the hose, the end and intermediate parts being reinforced by a wrapping which consists of at least one strip which consists or includes the elastic material. The hose is provided in a continuous length which may be cut at a selected intermediate part to provide a hose of the required length. To this end the intermediate portions have a length a twice the length b of the end portions.
