Moreover the invention contemplates a suitable fluid line (11) and a fluid power means belonging to it.

Abstract: A connection member for a fluid line (2) defining a fluid duct (5) with stranded signal conductors (7a and 7b) in the wall (4) thereof for the transmission of electrical signals. The connection member has a female socket into which the fluid line (2) may be inserted and in which at least one signal contact (26a and 26b) is arranged, which at the end may stick into the at least one signal conductor (7a and 7b). The penetrating part (27) is constituted by a knife edge (27a) whose width is equal to the diameter of the signal conductor (7a and 7b) to be contacted and which splits the signal conductor 7a and 7b) on penetration from the end into an outer and an inner line limb.

Abstract: 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.
