ABSTRACT:
A tool-less chain coupling link has first and second body members releasably joined together. A first hinge pin is movably positioned within corresponding openings in the first and second body members. A first hinge pin keeper member is pivotally attached to the first body member and movably attached to the first hinge pin. A second hinge pin is movably positioned within other corresponding openings in the first and second body members. A second hinge pin keeper member is pivotally attached to the second body member and movably attached to the second hinge pin. The first and second hinge pin keeper members can be pivoted in a first direction to withdraw the first and second hinge pins, respectively, a sufficient distance to allow the first and second body members to be released from each other. The first and second hinge pin keeper members can be pivoted in an opposite, second direction so as to position the first and second hinge pins within their corresponding openings in the first and second body members so that the first and second body members are releasably joined together.
