Cracked latch that holds the ink cartridge in place. What is the part number or how do I find it?

HP Officejet 250 Mobile all in one.  I cracked the plastic piece that latches to the ink cartridge and holds it in place.  I need help replacing that part but I don't know how to find the part number.

That's a pretty complicated part to replace, the spare part code is E0X34-60020

I don't think we are talking about the same part.  This is a tiny black plastic piece that pretty easily locks back into place (when it isn't broke).  It is about a square inch.  I included a photo of the part and the piece that cracked off.
