I call them "unavailable to buy".

These look proprietary to the manufacturer. You might contact them to see if they can be found somewhere else or even from them.

if you want to buy them by 1000 you will have no issue
I had an old string off icicle lights with that connector. I got an extension lead with those connectors way back. Don't know if you can still get them. Most standard strings now days use reverse polarity switching than having two channels and a common.

Make up your own lead.
use that existing end to connect to the power supply.
Note which wire is 1, 2 and 3
Cut the wire off a reasonable distance from the plug.
Purchase 3 pin connector from a vendor like Ray Wu or AHH
Connect the new male connector end to the lights.
Connect the female connector to 3 core cable extension.
Put the old male end on the other end of the 3 core extension.
Make sure you solder and heat shrink each wire join after you have confirmed the wire / plug connections are correct

I was going to suggest that same process.
Another option is to take some good end on pics of both halves of the connectors and see if the google image search can match them.
