How to restrain two plastic sheets in tension
(OP)
I'm working on a military protective structure and need to restrain two sheets of plastic (5mm and shaped) 300mm apart. The void in between will be filled with earth/sand to provide protection against a particular threat. The external side of the plastic sheet cannot have anything protruding to any significant distance and I need to find something that will hold them in position and resist the outward pressure exerted by the fill.
Does anyone have any ideas? Obviously I could use threaded bar with nut and large washe, but this would stick out too far and would mean personnel would snag themselves often.
Hopefully this is clear enough, but if not let me know and I'll try to produce an image.
Cheers.

What about a countersunk rivet head on one side and peen the other end of the rivet into a countersunk recess, obviously you would need some kind of spacer inbetween the sheets.

If it's relatively small, why not chicken wire?
If it's large, you will need some sort of framework, like a garden trellis, then chicken wire

Desertfox - I'm afraid you lost me, I'm not familiar with terminology you use. I do however understand the need for a spacer.
Irstuff - the sign I'm working on is a protective structure which the end user would erect to protect themselves. I'd really like to achieve an 'ikea' type build in which the builder couldn't get anything wrong and am therefore looking for simple snap fit connector. I'm sure that there's something outer there that does this, but it's just a case of find it. If not we may have to look at get one manufactured.
For now: I'm going to look into plastic rivet manufacturers and see if they can help.
Thanks again.
