How to attach glass plate

Any suggestions on how to attach the plate? I bought the gp8200 plate, but the clips recommended on the product page do not work well. Is there a double stick tape that can take the heat?

I am using 4 pieces http://www.rafoshop.cz/user/shop/big/406704(1)(1).jpg in center of glass. I think, size 9 or 16mm, do not know now.

This style of Bulldog clip is working for me;

If you have nothing else Blue-Tack works as well.

I have used successfully dubbel sided tape to glue the plates together. My temperature did not exeed 50 deg up to now. Eventually you can use high temp silicone kit (300 deg).
However, my findings with the glass plate are that the sticking properties are much worser than the original flat bed. For that reason, in my device the original flatbed is supported by the glass plate (4mm) to keep it flat. They are glued together with dubbelsided tape. I am very satisfied about the result.

Thanks, everyone. I don’t know why I didn’t think of the bulldog clips. I have a drawer full of them already!
