Yes, Ford used two basic wiper arm retention methods, both using tabs - one movable (like the link) and one fixed. Both are really easy to do. If yours has no movable tab, then it is retained by the arm pressure holding the side of the socket away from the arm in. That side has the tab. So, to remove, you rock the arm socket towards the wiper arm, which lifts the tab out of the groove on the other side. While holding this awkward position, pull up on it and off.
The problem is that pulling up also removes that pressure you're holding towards the arm, so a key or screwdriver is handy to lift that far edge up a bit. Once the tab is out of the groove, it will slide up and off without holding pressure. I hope that makes sense. I'll see if I can find or make a simple diagram to explain it.
