Probably the simplest is to use silicone sealer as the glue. If used sparingly, 
it will be plenty strong enough, and yet will allow future disassemblies. It is 
in some ways better than conventional glues, because it does not attack the 
plastic compound of the case.

Or, you can do as I did, and use 0.063" Stainless Steel Safety Wire, thru holes 
drilled in the tabs, AND the thin bead of silicone.
