I broke the ring on a M.2 Wi-Fi card, but installed the cable onto it anyway. I think the part I bent off will probably rip off and get stuck in the cable the next time I take the connector off the card. Here's hoping I'll never have to do that...

I believe those are MCX. My Shure SE215 IEMs (earphones) use the same connector.

Those connectors are good for one connection and no disconnections.
