The ones I've seen, but not used, were generally held in place by springs attached to eyelets installed under a few pan screw heads. Usually 4, one on each corner of the heater pad. As for shielding against mechanical damages, I think I'd install an 'off- road' skid plate & let the big stuff bounce off it.
