Need Help Finding Shoe Repair Hardware

[addisonshopper]

Ladies, please help me in locating this type of hardware. This is how its supposed to look.. I need one exactly like this for the other shoe..
These are from my favorite ( well one of them) pair of Chanel Sandals
I don’t even know the name to call it, or I would google it.
I have taken it to a several shoe repair places and they cant fix it.. I guess I got to hit a cobbler or something..

Did they break? Why don't you send them to Chanel to repair them?

the metal piece that I needs unscrews from the leather..
