Abstract: A coupling link for coupling two chain end portions to each other. The link body (1) is elongated with a length corresponding to at least twice the greatest width thereof, the link body being widest at a central portion. Each opposite end portion (2, 3) of the link body is formed as a fork-like portion with a transversal anchoring pin (7) for securely anchoring an end link of the associated chain end portion, whereas the central portion (4) of the link body is provided with a central opening (12) permitting insertion of a desired chain link (102) so as to enable the formation of a non-loaded shortening loop of at least one of the two chain end portions.
