Went by the NAPA store in San Jose couple weeks ago and the guy had a box full of them
so I bought a few extras for my tool box...
NAPA 725145 - connector, male crimp, spade
NAPA 725147 - connector, female crimp, socket
I was surprised when the guy said "$0.59 apiece" for the male connectors;
I think I saw'em on the NAPA website for $0.75 each.
