Abstract
Abstract A coupling device having an integral metal member folded over on itself forming two parallel sides which slidably receives another integral metal member folded over on itself; the first member having an opening in the top thereof for receiving coupling loops depending upon its slidable relationship with the first member; the second member having at least one outwardly protruding blister on each side thereof for actual slidable contact with the inside walls of the second member and maintaining a spatial relationship when assembled so that the entire coupling device can be plated after assembly.
