Duct tape patch looks like no hose on it. Part is the intake manifold.

 

It doesn't look like it from the pic. It cracked last night and is pretty flattened out. At the crack its in a u shape. The tape is holding out for now.

It has what looks like a hinged clamp but I cannot see it enough to see how it works.

Bigger connector you simply push in both sides to release it to come off and simply push back on when done. Two opposing tabs to push in on.
