Electrical connection O2 sensor stuck

Good Evening,

I have replaced my upstream O2 sensor in the past because it was malfunctioning in December 2020.

I believe I have to replace it again because I am getting error code P2243 (in addition to P0420, which I have accepted as permanent). The vehicle itself is idling roughly when stopped, and on two occasions, completely stalled. It was able to be restarted afterwards.

However, while I was prepared for the screw-in end of the sensor, I was not prepared for the electrical end of the sensor.

The sensor in question was this that I'm replacing: KAX 234-5107 Oxygen Sensor,...

I have no idea how to get this apart. The black piece does not pull apart. I tried squeezing the other end with pliers, and sliding in a screwdriver, but neither one of them is working. Is there a way to get these apart? Thanks in advance

I hope that’s not the sensor you’re going to use. Looks like a no name POS.
