Abstract
The invention provides a retaining device for assembling two panels together. The device has a support and first and second pairs of spaced-apart parallel walls extending along the support and projecting outwardly therefrom for providing first and second holding channels extending angularly to each other, each channel being adapted to receive an edge of one of the panels therein in a snugly relationship to allow assembling of the two panels. The invention also provides a formwork for forming a polygonal upright concrete structure using a plurality of retaining devices and a plurality of panels arranged with the retaining devices for providing a forming cavity between the panels adapted to receive concrete therein. There is also provided a packaging assembly for packaging goods using a plurality of retaining devices and a plurality of panels arranged with the retaining devices for providing a protecting cavity between the panels adapted to receive the goods therein.
