I wonder if any of you might be able to help, I'm looking to find these heater hose clips. Would anyone be able to identify them? Many thanks in advance.

I've just purchased a 2009 Defender 2.4 TDCI. Everything works perfectly on the vehicle part from the rear heated window. When switching on the light appears on the switch, and the relevant light appears on the dash. Everything looks good apart from the rear view which remains totally fogged up...
