What about carefully drilling a couple small pilot holes in the body, along the perimeter of the cover, and then installing a couple self-threading pan-head screws? That might give you enough of a flange to keep the cover in place. You would need to use short screws of course, so you don't screw into some circuitry.
Or use lots of washers.
If you position them right, you might still be able to slide the cover off when you need to replace the batteries.
Yeah I looked at my AF 360FGZ, and if my tabs ever break, as you pointed out, there will be no place to wrap some kind of reinforcing strap of velcro or gaffers tape or anything. Not even a good place to slip a large springy loop of plastic or metal over the whole thing, without covering up some important bits.
