using plastic and an elastic band on it at the mo....

how much is a new one please

Your coolant header tank?

Plastic and a rubber band will not be sufficeint, needs to hold one bar pressure, you will boil over and overheat your engine.

How'd it come undone - usually they're done up pretty FT, to coin Ross' phrase

edit: You checked your engine tray its not fallen down? Tap it from underneath see if you can hear it jumping about down there
