2001 Dodge Stratus Winshield washer

The hose that connects to the windshield washers on
the hood have come loose. It will be simple to put
it back on but I am unable to remove the insulation
panel that covers the interior of the hood. It has
some plastic devices that are about the size of a
quarter with slots on four sides that are somehow
connected to the hood. How do I loosen them
to remove the insulation panel.
