Toaster lever clip part name?!

I'm trying to repair my toaster - I turned it upside down and banged on it a little bit to get bread crumbs out, and after that one side wouldn't stay down. My wife loves that toaster so help me fix it please!

I watched YT videos and followed cleaning steps and nothing worked. I opened up the toaster after that and comparing the two slots, I noticed that the "clip" or "locking mechanism" on the side that wouldn't stay down seemed broken. It's the tiny plastic curved arm at the back of the part that is broken and the latch won't engage. I can't seem to Google the right key words though to find a replacement for the part - what is this called? And where can I get this from?
