Help! I Need to Replace This Part and Don't Know the Name!

[Patrick M.]

Hey there- I am getting rental #2 ready for showing and as I went to re-install this piece of the bathroom vanity, I noticed that one of the two plastic items that secures it in place is damaged. I've been googling "vanity plate clip" and "vanity plate securement device" and all sorts of other terms, but I don't know what this is called. Anyone know the right term, or whether I'm going to likely find a replacement at HD/Lowes?
