Lol my grandad had some kind of surgical machine hooked up to him a few months ago - it had the exact same white clips on the tubes.
These got replaced everyday so I've got a bag of like 50 of the suckers somewhere, can't seem to find them now!
Call up Bluecare and ask one of the nice ladies lol

OR
On a slightly less weird note - We've got a set here - $5.50 for 7x Cabrinha ones. (07) 3284 1186 if you want them...
