Replacing PCV valve on camry 2009.

Me again, I recently got helped with finding a new battery(it works great!). Now I'm replacing the PCV valve, I know how to do it in theory from watching videos on youtube of similar model camry's but mine appears stuck. I can twist the hose but I can't pull it off in the slightest.

One thing I noticed is people just pinching the clip with pliers and pulling off the hose in videos, of course no one has any issues. I was wondering how a dealer or mechanic would remove the hose? Are there any special tools for removing it or do they also just pinch and pull? I don't mind breaking the hose and simply replacing it, but even Scotty Killmer on youtube just does the plier trick and doesn't use anything to loosen it up.
