Abstract: The invention concerns a safety hose made of elastomer material and/or plastics, in particular for conveying environmentally-harmful substances and comprising: an inner layer; an outer layer; and an embedded rigid carrier in turn comprising two rigid carrier systems, each of which comprises one or a plurality of layers. Disposed between the two rigid carrier systems is at least one separating intermediate layer, the rigid carrier system facing the inner layer having a low extensibility and high chemical resistance to the substance to be conveyed, whilst the rigid carrier system facing the outer layer has a high extensibility. As a possible variant, an adhesion system can be provided between the rigid carrier system and the outer layer. The adhesion system comprises a radial, helical or axial two-zone system, the one zone having a lesser adhesion effect than the other zone.
