Not with the tension modern clamps have. But if you buy the correct tool the modern ones are a breeze.

 

I've always used channel lock pliers. I didn't know there was a proper tool..

 

A pair of lineman's or electrician's pliers have a wide jaw and will spread those easily.

 

IF the access is there, I used vice grips. Problem is, many times there isn't a good straight sideways shot.
The pliers in this ad with the box end are for the big ones and I've seen them work pretty well. Never owned a pair, though.

Engineer types have told me that the spring style is a better seal than the worm screw style, because there is always clamping, not a set diameter. I have not had a properly located and tightened clamp fail, it's always the hose or poor install. OR it's on a line without a flare, allowing the hose and clamp to slip.

 

I've always used whatever shitty pliers I have nearby, never had an issue with those clamps, and actually prefer them over the worm gear clamps. I like to point the tangs down when I reinstall, just for a cleaner look. A trick you can do is use a zip tie over the tangs to open up the clamp, and keep it open, then just yank on the tail of the zip tie to get it off when you reinstall the hose. Some of these clamps require more force to open, so the zip tie trick doesn't always work.
