That little support arm...?

This fixture had been Glued a long time ago...I do not remember how or why. Must have been in a hurry or something. But it came loose again...so I glued it again. And this time I took a picture. How would you go about repairing this?

Billy,

MarineTex has worked well for me in similar situations, clean real well and clamp 'til cured stuff is tuff.

or

If there is enough clearance on the outside of the frame.

Some would say rivet, but I would go with a couple of 1/8" stainless machine screws with flat and lock washers, that way you can tighten it should it loosen up.
Plus rivets may tend to loosen/shear over time.

I would rivet it back on as it was originally
