O2 Sensors

I am replacing the #1 O2 sensor on my 1997 Toyota Camry 6 cyl non-Cali model LE. My question is how to you get the connector apart. Is there a tab that must be pushed in for it to seperate? I tried pulling it but it doesn't come apart..Any ideas will be helpful. I thought the hardest part was going to be getting the bolt loose, but that was easy, getting the clip apart is hard. I am using the Bosh OE O2 sensor as a replacement, any thing I should know when replacing with the new sensor?

Thank You,
Mike

Are you sure you don't replace the sensor and the wire as one piece and disconnect the sensor at the connector on the other end of the wire?

If this is the connector you're talking about, there is a tab and it's obvious. I must be missing something.

The O2 sensor is one piece. I can't seem to find the tab that will release it. I will check again in the morning if its that obvious to see, I may have just overlooked the tab...
