There are two plastic wings that hold it in place. It looks like one or both of yours are snapped off. This cable in my Pushbutton car had a problem with the chrome peeling off. I got the last one that Wilkinson had. It was used and one of the wings was missing. I improvised with some epoxy (or something like that). Maybe you can use a small hose clamp formed into a square shape to secure it.
