The fit is super tight on nearly all clips I have encountered minus the well used sebenzas. This super tight fit is due to the super tight tolerances of a Sebenza. You have to blasted finishes gripping together if that makes sense and super tight tolerances....! The result, what your encountering.
Remove the screw and work the clip up and down. Do Not bend it straight up as you will bend the clip. Just work it up and down and it will pop out. This question came up about a week or so ago and that was my reply. I have had this happen to me many times and every time, this solution worked perfectly.
