A chain shortening device is described. The device has the general shape of the letter "C". A single slot ( 20 ) extends longitudinally along the elongated body ( 10 ) of the device. The single slot has a central widened portion defining a lead-through opening ( 20 E) through which a loop of an associated chain can be inserted, whereby the device can be handled as a separate unit and be attached sideways to an associated chain.
