I recorded a video and I had to use 2 hands so I didn't get the exact thing of what I did so I explained it and took a photo of the annoying clip in question. If there is any other clarification needed let me know.
So the photo shows the female receptacle for the clip that you marked. This is from the opposite direction so I added a diagram of approx how the pin fits in. The two tabs on either side, you may see me pointing it out in the video although the first video didn't save for some reason so I'll double-check to see if I got it all. If not I'll have someone hold the camera for me so I can show it.
Sorry that it is broken up the first video stopped and then I set the phone down a few times.

If these don't help, let me know which area I can give you a better close-up or clarification of.
