Connector help!

I need to buy some of these, mostly just the female part and I am having a hard time finding these connectors.
Seems like this should be easy, but it just isn't.
See attached image please.

Other socket is same shape, cut away to allow this one to be inserted one direction only.
I will though. Compare and then get some of these.
Funny, one sees this stuff all the time, yet it can be brutal trying to source.
I super appreciate it!
