Need help ID'ing a part

[mrlax]

Folks, I have no idea what this part is called, but I need help ID'ing it and if anyone has some for sale, please let me know.
Basically, these lock-in to the back of our DAIICHI model machines, and engage the shooter when turning the handle. Without them, the handle turns but will not launch the balls. I have a variety of similar looking pieces that perform the same function, with the same pin count/plug-in

So they are pretty important. Anyways, we have a need for a few extras, and I wanted to see if anyone had these to sell, had advice on what they were called, etc, before I went through Japanese channels.

Thanks!

I call those a "dongle". I thought I saw a thread on how to make your own.

Member Dave Rob sells one with more functionality. I highly recommend it.

He calls it a card reader emulator.
