A plastic hose, and more particularly a pneumatic hose, is provided with at least two electrical conductors extending along the hose body. These conductors are in the form of strips (11 and 12) of a metallized braid of plastic material or of natural fiber with a spacing apart on the hose body (13). Accordingly high flexibility of the plastic hose (10) is achieved with satisfactory electrical conductivity of the strips ensuring safety as regards breakage.
