Abstract: A tension member with at least one loop made from fiber-reinforced plastic, which tension member has a plurality of fibers that run substantially parallel to each other, so that the loop is formed by the plurality of fibers, wherein a first group of fibers is turned over along the loop in a first turning direction, while a second group of fibers is turned over along the loop in a second turning direction, which is opposed to the first turning direction.
