Yes there should be a little tab were it's splined. You pull the tab out and lift up. I had stripped 2 wiper arms already.Don't remember for sure, but I think they have a little retaining clip you pull out. Just pull up on the wiper and let it bend at the joint. Once bent up, you can take a small screwdriver (sometimes your finger) and slide out the small retainer as far as it will go. The wiper should pop right off. If not, just try to rock back and forth until she comes loose. I don't think the clip will slide out without bending up the wiper arm at the hinge. Hope this helps.
