ABSTRACT:
An expansion bank linkage of the type having an outer row of outer links and an inner row of staggered inner links, clips conencting each of the links of one row with two links of the other row and a spring in each of the links for resisting displacement when the linkage is stretched longitudinally. The improvement comprises a plurality of first and second clips having flat inner and outer legs connected by a central portion arranged to skew the legs with respect to one another. The first clips are skewed in an opposite sense than the second clips, the clips being arranged so that a first clip leg and a second clip leg are disposed adjacent one another in each of the links whereby the inner and outer links are held in laterally spaced relationship along the length of the linkage when it is in a relaxed position.
