Just to throw one more option.  They’re also called ear clamps.  Oetiker is a big brand name.  Their tool is much like what ORR showed you but has both straight or side cut which can help with some of the odd angles.  They are really easy to install on all those little oil cooler hoses and fuel hoses.

Thanks guys. You got me pointed in the right direction. Crimp clamps are
indeed what I am dealing with. the beggars are from the factory and on
every hose in the engine bay. This is going to be fun, changing all the
engine bay hoses. The bloody things appear put on with the intent they
would never come off. there is a tool to crimp them tight, but no way to
remove them shOrt of cutting/grinding them off. And on fuel lines that's a
no-no. ONE WRONG SPARK AND AND YOU'VE A HELL OF A BONFIRE FOR YOUR
MARSHMALLOWS!.

Any suggestions?
