Improvements in hoses, characterized in that these are flexible, extensible, are reinforced and comprise an elastic and helical reinforcing winding and a deeply corrugated tube, composed only of thin elastomer material and prepared with helical corrugations open towards the inside and the outside, unoccupied, while the first contains the filament of the reinforcing winding and, furthermore, because at least in part of the hose, the reinforcement is locked to the pipe, along a zone of the bottom of the corrugation in which the surfaces are in contact in all cases in the extended position, but said surfaces are free to separate into adjacent areas, where they are in contact in the normal position, but not in the extended position.
