The invention is intended to provide a connection between the panels that comprise the non-perforated honeycomb-type floating internal membrane in a highly effective manner that, although similar, is yet completely different from designs already on the market, owing to a novel design and construction, the principal characteristic of which is to combine similar characteristics of other designs, but more effectively, safely and durably.
