Abstract
Abstract A coupling or chain connector device is disclosed comprising a first coupling member cooperable with a second coupling member. The second coupling member has a tortuous path between the inner and the outer regions thereof. The tortuous path comprises a first through fourth substantially linear sections and a first through third interconnecting sections sequentially interposed between the first through fourth linear sections. The first coupling member is at least partially receivable in the second coupling member for passing the first coupling member through the tortuous path to couple the first coupling member to the second coupling member. The first coupling member may take the form of a linear wire or bar or may take the form of a substantially ring-shaped structure. The first and second coupling members may be incorporated into a unitary structure with the first coupling member established on one end thereof and the second coupling member established on the other end thereof. In this configuration, a plurality of coupling members may be coupled to form a chain structure.
