From speaking to the mechanic apparently there's nothing obvious wrong with the pipe. It seems that the connection between pipe and injector is an interference fit so maybe over time it has just worked lose. If this is the case then using a second hand injector fuel pipe would probably not seal either.

The injector pipes are screw on (union) fit. They are under considerable pressure, and would never be interference fit. The pressure at the injectors, even on an older diesel, is sufficient for fuel to pass through human skin if a hand or arm is exposed to the spray.
The small leak off pipes are push fit, and any fuel resistant rubber pipe of the right diameter can be used.

Thanks DP - you are right, the injection pipe does screw on. The garage unscrewed this when they first looked at the leak. After screwing it back on the leak was much worse. This would suggest the leak is something to do with this screw joint.
I spoke to a couple of garages this morning about doing some sort of temporary repair. Both were negative. One said we don't do that sort of thing these days - not allowed...
I have now decided to wait for the new injection pipe to arrive from Mazda. Hopefully the long delivery time quoted was pessimistic. In the meantime we will be hiring a car and using the bus.

Go to a proper diesel specialist (not a car dealer) and have a new pipe made up. This is absolutely simple basic stuff to the right people.

Updating this thread - I did try several proper diesel specialist but getting a new pipe made up was beyond them.
Anyway the correct injector pipe has now arrived at the Mazda garage. I called the garage (not dealer) that investigated before to book it in to get this fixed. However they are asking if the injector itself is still at the dealers as they think it needs both an injector and pipe.
Speaking to another garage before when I tried to get a quick fix done, they thought that it would only need a new injector pipe.
So who is right? I know this is a difficult question but do I really need a new injector, at considerable expense, or will the new injector pipe fix the diesel leak?
FWIW the mechanic who checked out the leak originally couldn't see anything obviously wrong with the pipe.

Thought I should update this thread with the conclusion incase anyone's interested..
Well after a long chat with a mechanic at the garage I decided to fit the new pipe with the old injector. The reasoning being that the injector pipe was likely to be the part that was faulty and the injector was the harder metal of the two so a new pipe should seal.
Unfortunately the new injector pipe didn't cure the diesel leak although it wasn't as bad as before. I was now faced with getting a second new injector pipe and new injector at considerable expense, plus another long wait while the pipe came from Japan. The garage advised that to guarantee the seal a new injector pipe had to be fitted with the new injector.
I couldn't wait for the parts to arrive so decided with a heavy heart to trade the Mazda in for a nearly new Merc. It was sad to see it go as it had been a very good car until the last few months. Just hope the Mercedes is as good.
