Heat/Water Valve Leaking

I need help diconnecting the hose with the yellow arrow pointing to it.....I've never seen a hose clamp like this before....does this clamp need a special tool or a trick to pulling the pin?

i would just cut it off,and replace it with a regular clamp

 

Yeah....but is it there for a reason?????

 

DON'T PULL THE PIN! It will explode!

j/k. No. replace with a regular hose clamp.

Are you replacing the hoses, too?

 

It will untwist but like every ones says replace it with a gear clamp.

 

The hoses are in great shape....and i'll replace the old clamp with a regular, new one....thanks.
