A mating and fixing device (1) for disposable forms made of plastic material for obtaining sanitary voids, ventilated air gaps, crawl spaces, ventilated floors and roofs, which have an upper surface (4) blended, at the corners (5), with vertically arranged lateral legs (6). The device is constituted by at least one tab (11) which protrudes substantially longitudinally with respect to the lateral legs (6) and cooperates selectively with at least one seat (16) provided at the lateral legs (6). The tab (11) and the seat (16) have a configuration and an arrangement which are adapted to allow the stacking of two or more forms. |
