Best way to reattach this piece to frame?

[Mr. Cow]

Apologies but I don't know the name for this part, but its a metal piece which sits on the inside of the rear wheel dropout (derailleur side). It's fell out but currently held in by friction. What's the best way to reattach it to the frame? I think it was "bonded" somehow rather than screwed as it seems to fit perfectly round the screwheads for the derailleur hanger bit?

Bonding it with adhesive would make sense. I'd guess it was to protect that side of the drop-out.

Yes, you're probably right but what sort of adhesive should I buy?

Is it held in place when the wheel is in place. If it is, it'll explain the friction fit.

Edited to ask
What are the two materials, and bear in mind the finish of both when deciding on what to use, glue/adhesive wise.

It’s a friction fit, if you want to secure I’m sure a little cyano would work but maybe not a permanent solution.

Thanks, is it just a super glue job then and is it safe to use on carbon?

A smear of PU adhesive such as Sikaflex or Tiger Seal will do the job and will be carbon safe.
