Anybody know the name of these clamps?

They are often called "Oetiker" clamps -- but that's just one brand name (and Oetiker makes other style clamps):

One might also call them a "crimp clamp" or an "ear clamp".

 

Oetiker clamp

 

I needed to repair an air line. I bought an assorted set on Amazon. They were called SS single ear hose clamps. I used an old fashioned nail puller pliers to tighten the clamp, and it worked well.

 

You can get them at any hardware store that sells PEX plumbing, you'll just need the crimp tool. I remodeled my master bath and they were great to work with.

 

Often called "pinch clamps" but
Oettiker is one of the companies that made them famous

Mcmaster has them in virtually every size both metric and SAE, and in any material you could want, including titanium.

I use them on everything that isn't regularly serviced/removed. They handle port injection fuel lines at 80+ psi. Once you properly crimp them, they are VERY strong & secure!

I like the pliers that have front AND side pinchers; great for tight engine bays:
