Abstract: The present invention relates to a coupling device for chain links (1) which comprise an elongated element (2) and which are provided with two pairs of eyes or loops (3, 4 and 5, 6 repectively). The coupling device (11) comprises a double-hook member (13) and is designed to cooperate, in a coupling position (K), with the eyes (3, 4) in one of the pairs of eyes by engagement from within of said eyes (3, 4). The double-hook member (13) is sized such that it is insetable into the chain link (1) through an interspace (9) between the shanks (7, 8) and connecting parts of the eyes (3, 4 or 5, 6) and then locatable or positionable in said coupling position (K) in the chain link (1).

Abstract: The invention relates to a chain link and a method for the production thereof as well as a chain consisting of connected chain links and a connecting part for connecting chain links. The chain link consists of an endless elongated rod-like part (1) which is characterized in that it is shaped as two pairs of loops (2, 3) and (4, 5) wherein the loops in each pair are substantially parallel and the pairs are arranged in two planes which are turned through 90.degree. with respect to each other. The connecting part consists of a semi-finished chain link and the chain consists of connected chain links as well as possibly connecting parts.
