I was told to push the flat side of the plastic clip. I screwed with it for a few seconds and it came off. getting it back on was a little more difficult, but no big deal HOWEVER, when I went to remove it again I couldnt' move it. I don't know what I did the first time that I was unable to do the second but I would try squeezing the thing, like the earlier post says. I thing I pushed the cable in towards the instrument panel and spun it a little (almost like a prescription bottle).
