ABSTRACT:
A close coupling strut for interconnecting multi-faceted joint elements is comprised of paired oppositely-facing, in line, elastically compressible clips which are separated and joined together by an intermediate bridge. The bridge is configured to separate the clips, which snap fit into mating joint openings located in the facets of the joint elements, and to release the clips for removal from the joint openings upon application of squeezing pressure thereon. Extension means are attached to each side of the bridge and extend outwardly thereof beyond the joined facets of the joint elements to facilitate squeezing of the bridge means when the user's fingers cannot be inserted between the closely spaced joint elements. Each clip has a V-shaped tip with ends that are separated by an overall transverse dimension which is greater than the height of the opening in the joint elements, and the bridge means has an overall transverse height approximately equal to the height of the joint openings. Therefore, as a clip is forced into a joint opening, it is deflected inwardly until it is inserted past the end of the tip where it again expands to its relaxed position thereby becoming locked into the joint opening. The clip is elongate in cross section to non-rotatably fit within the majority of the joint openings, which are similarly shaped, and to rotatably fit within those joint openings which are circular, thereby serving as an axle to allow rotation of one joint element with respect to another.
