ABSTRACT OF THE DISCLOSURE A tendon for use in pestressed concrete is made up of a plurality of individual elements such as strands of steel wire arranged in a uniform array around and spaced radially out- wardly from a center point. A spacer for the tendon includes a star-shaped base formed by arms extending radially outwardly from a central part. The central part and the arms define triangularly shaped openings for receiving one or a number of the tension elements. An intermediate part is positionable within the triangularly shaped openings for separating the elements located within the opening. The intermediate parts have a radially extending web and a flange extending trans- versely of the web for dividing the opening into separate spaces for each tension element. During assembly, the base is inserted into the tension member for separating the tension element and then the intermediate parts are inserted for spacing the elements from one another. The spacers are in- tended for use at a change in direction point of the tension member and initially are assembled at a positon spaced from the change in direction point and then are moved to the point.
