Once the door panel is removed and you access this clip, you will see that the rod is threaded. That is because this gives you adjustment. So you pull up on the yellow part of the clip that you cannot see in your picture. Just take a small flat head and pop that up where I am pointing at in your picture below with number 1. Then number 2 is the hinge that the clip opens on and then you can remove the rod.
This is a video of a different truck but it has some good info that will help with this process but that clip is pretty easy to get off once you understand how it comes apart:
Please see the picture below and let us know if you have questions on this.
