DEFINITION
Classification: 24/573.2
And linking cavities in adjacent parallel panels:
(under subclass 573.1) Separable-fastener* wherein the dissociable member (a) enters a cavity formed in each of two distinct planar structures composing the structure-to-be-secured* or the support therefor, (b) connects the planar structures to each other, and (c) maintains the structures in parallel, noncoplanar relationship while connected.
