ABSTRACT:
This invention relates to a coupling link comprising a first half line and a second half link, each comprising a unitary member with a pair of spaced ears at one end, a tongue at the other end and a central body member which joins the ears and the tongue. Bores in each of the ears of the first and second half links are aligned with a bore formed in the tongue of the opposite half link when the first and second half links are mated to form a coupling link. A link pin is received in the bores formed in the pairs of ears of the two links and in the bore in the tongue of theopposite link. Each link pin is retained in place by a pair of pin keepers each received in a slot formed in one of the ears to close the pin bore in that ear. Each pin keeper includes a tang which projects from one of the slot openings in the ear and is bent out of alignment with the slot opening to retain the keeper within the slot.
