A connecting element for connecting two link chain strands comprises a central oval chain member, and two coupling links each having an axis and two axial ends and connected to the chain member and one of the link chain strands. Each coupling link is composed of a U-shaped suspension part and a W-shaped base part whose legs and projections interdigitate with one another in a comb-like manner. A coupling bolt extends through the legs and projections so as to connect the base part with the suspension part of each coupling link. Grooves of the base part which are bounded by the projections, extend from a front end face of the base part through the region of the coupling bolt and further up to an axis of a through bore through which latter the chain member extends. Side walls bounding these grooves and located adjacent to a longitudinal axis of the chain link diverge outwardly in the transverse direction in the region outside of the coupling bolt and near the through bore. The transverse cross section of the legs of the suspension part corresponds to the transverse cross section of the central projection of the base part.
