A non-tangling line of conveyance includes a flexible outer and non-extendible tubular hose. Within the tubular hose a flexible non-extendible body member is placed. The body member is of a material that includes a plastic memory especially against torqueing. The body member is restrained against any substantial lateral movement. When the tubular conveyance is twisted in any direction, the inner body member undergoes a like motion. However, if the twisting of the tubular hose is released or ceased, the memory torque within the body member tends to force the line of conveyance into an untwisting state, thus avoiding any tangling, knotting or kinking of the conveyance line. The inner body member is restrained against substantially lateral movements by a multiple of electric conductors that are wrapped around the inner body member. In another embodiment, the inner body member is restrained against substantially any lateral movements by having a multiple of edges of said body member fitting snugly against an inner wall of the tubular hose of the conveyance line. |
