What is the plastic piece that houses the endpoints inside a USB port called?

I accidentally pulled it out and broke it somehow. The USB port itself still works however, it seems that plastic piece is what keeps USB connectors plugged in because if I plug in anything now it's quite loose. Anyone know what this piece is called and if it's something I can repair easily?

EDIT: For clarification, I'm talking about the white piece inside the USB port here:

This isn't my computer btw. But like in all USB ports, they have this plastic piece inside which I pulled out and now you can see four metal prongs.

Thanks!

Solution 1:

The USB specification doesn't give it a name - you could call it "the USB type A receptacle contact support tang":

Since the tang ensures the orientation of the plug, it also acts as a key.

This tang/key is not replaceable. To repair a USB port with this part missing it is necessary to desolder the whole USB connector from the PCB. This needs good tools and technique otherwise you will lift and tear pads and tracks on the PCB. So best left to an expert.

These connectors usually have a metal shell with though-hole securing pins with a high thermal mass that needs a lot of heat, endangering nearby components. The data pins are typically small surface mount pins and need much less heat and much more care to avoid lifting PCB pads and tracks.
