How to replace kelsey Hayes disk brake hoses on Dart?

I'm trying to replace the flexible disk brake hoses on my 67 Dart. I have included two pics of the mounting bracket that the hose connects to. I can't figure out how to unhook the rubber hose? Taking the metal brake line off no sweat. I have correct replacement hoses that have a c shaped clip on them. I can see the clip on then underside of the bracket but haven't tried to unhook. I looked in my 67 dodge service manual but it doesn't go into specifics on removal of hoses. Any help greatly appreciated.
