A retractile telephone cord of this invention has a retractility which decreases substantially linearly from each end to a center of its length and an extensibility which increases substantially linearly from each end to a center of its length. The cordage includes a plurality of conductors which are individually insulated with a first plastic material and which are disposed in a planar array, and a jacket of a second plastic material which encloses the array. The jacket is formed about the array to provide a cross-section transversely of the cordage which includes at least one side that is parallel to the array. In making the retractile cord, a length of the cordage is wound helically about a mandrel with the one side of the cross-section of the cord being in engagement with the mandrel. This prevents any axial twisting of the cordage as it is wound on the mandrel and subsequent to the heating of the cord and the reversing of the direction of the helical wind, results in a cord having the above-mentioned retractility and extensibility properties.
