The plate underneath that LED emitter *is* the heatsink, if it's anything like the Luxeon product it's patterned after. The emitter has an exposed metal surface on the underside and the contact with the plate after soldering the lead tabs down is enough to hold it in place and provide heat transfer.
The junction between the emitter and the plate is too hot for SuperGlue, say if you were to pop the emitter off and glue it to something else, but I'm not sure about the heat transferred through the plate. Two-part epoxies are generally more resistant to heat.

Thanks Mike, I took a heatsink out of an old computer and want to attach the plate to the flat side. I read somewhere on the net a guy was using silicone II. I don't knwo about that one. Would it work to hold it down with a couple of small screws in those notches?

You could screw it down just make sure to only go finger tight so you don't risk damaging anything, and put some sort of insulator over the top under the screws to ensure they don't short anything.
