Unfortunately right at this moment all the print options don't work as if I try to print it just pushed the pipe out and up and spools unmelted plastic into the air.

Get yourself a bag of these: http://www.amazon.co.uk/dp/B006PF1RBK/ref=pe_385721_37986871_TE_item
(As Don suggested above)
I think these work better than the stock UM items as the locking portion is thicker so it tends to close the collet up more.
the bit that fits in to the t junction is all I need. Really is that simple isn't it. B&Q in the morning.
You don't need to use the clip. Instead loosen the 4 screws quite a few turns - maybe 2 or 3mm of gap. Then shove the bowden in as far as possible and re-tighten. The compression should be enough to hold the bowden-holder up without needing the clip.

Ewwwww..... I'm sure this works, but yuk! ;-)
and if you tighten it to much you probably shorten the lifetime of your PTFE and bowden, i guess to much pressure wil increase deformation of these parts.
If it won't stay put by itself, then I'd have thought something like a paper clip would serve as a temporary measure, at least long enough for you to print off some collet locks from that OpenSCAD script I linked you to. Or even a bit of 1mm cardboard cut to shape with scissors.
I built a temporary clip using a plasticard tube.An a soldering iron.
Then put the pipe in that and yeah so far it works, but I think the direct sunlight on the back of the machine will probably degrade the plastic once more so need to reposition the thing in the office away from the patio doors.
I believe we've been talking at cross purposes. I now think you mean the collet - the bit that encloses the tube, rather than what I would call the (retaining) clip.
Never mind, that plumbing fixture has both, and since that gives you 9 connectors for £5 you hopefully already have it by now!

No way I'd pay UM parts prices and shipping (and hassle) for that! I bought 6mm tubing from Amazon.co.uk. I also bought plastic plumbing parts that (if you look carefully) provides the bowden clips and collets (x9). E.g. :-

I admit that I've not actually tried the hose yet, since my original tubing is still perfectly ok. That plumbing fitting provides the complete fitting: collet and collet clip.
I've also previously posted an OpenSCAD model to let you print your own collet clips :-
