11 plate 1.6 Tdi SE coolant hose supports between engine block & expansion header tank

Hi

Limbering up a for a fuel and air filter change (Haynes DO skim over some important bits, don't they?    ) and I noticed the coolant hose to the expansion tank seemed to be hanging loose. So loose in fact the underside was chafing against the alternator pulley! I can't see any obvious supports. Are there supposed to be any?

Thanks
