Abstract
A self-supporting transmission line carrier between a moveable consumer and a stationary connection comprising a row of tubular members of any selected cross-sectional shape which are pivotally connected with one another and engage in one another. The tubular members are angled-off from the extended position only in one direction, in a manner whereby the angling-off of the tubular members is limited relative to one another by means of abutments. Each tubular member on one end has an inwardly rimming, circulatory channel, the outwardly angled-off edge of which forms the inner abutment. Each tubular member is shortened on the other end on one half by the width of the channel and has a circulatory inwardly directed angled-off edge which forms the outer abutment. Two adjacent tubular members engage behind one another with their inner and outer abutments and the maximum angling-off is fixed by the width of the channel.
