A plate-link chain, in particular a toothed plate-link chain, is composed of adjacent plates and opposing plates that form chain links by sets of the link plates. One or more spacer elements are installed between adjacent link plates to enable assembly of a wider chain at a reduced chain weight as compared with a chain in which additional link plate sets are installed to increase the chain width. The spacer elements have openings to receive hinge pins that pass through the link plates. The openings of the spacer elements can include pairs of openings, a single oblong opening, or openings that include gaps to enable assembly of a spacer element in a manner similar to a spring clip.
