ABSTRACT:
This invention relates to flexible hoses having a rubber body and a flange at each end thereof. The rubber body is strengthened by a reinforcement comprising continuous metal elements extending from one flange to the other and whose ohmic resistance from flange to flange needs to be high. The surfaces, of said flanges situated facing the metal elements of the reinforcement are covered with an insulating layer formed from a glass cloth having high mechanical strength and high electrical resistance and from a firm binder of high electrical resistance comprising an epoxy resin, the insulating layer adhering to the metal surfaces of the flanges and to the rubber body of the hose. The layer of glass cloth preferably consists of a plurality of plies which are superimposed and having filaments whose respective axes are at an angle of 45.degree..
