As per title, how do I resolve, do I :-
1. replace pipe and therefore has anybody got one, please?
2. cut off the connector and use a cir-clip?
-
After accurate checking (might be some deposit inside) I would cut connector off, I bought my car without them, they certainly were cut off by previous owner, I am using no leaking at all. My car is 19 yrs old still in good condition. :y
Good luck with it mate! :)

If you cut connector off use a hose clip not a circlip ;)

I'd personally use Jubilee Clips with a thin piece of rubber beneath (some bicycle inner tube) as a protection to the hose.
Provided you don't do what most people do (tighten them until they damage the hose), they will be fine. Very easy to fit, very easy to adjust and cheap.

Thanks for the suggestions but confused as to difference of a Hose Clip and a Jubilee Clip?

the difference between a ball point pen & a Biro ;) ;) :y

..... and use a cir-clip?
This is a circlip ......

OK you're correct was not going to use a cir-clip but hose clip ;) ;) ;)

As we're playing the comparison game,
This is a proper hose clip;

I'll give you that! :y :y

Hose clips expand and contract with the change in temperature of the pipework, giving an almost constant force on the rubber join. The force is determined on manufacture and is not adjustable.
Jubilee clips remain fixed and as the temperature of the pipe increases and the pipe expands the clip pressure on the pipework increases and the clip digs in to the hose, potentially causing early failure. The force exerted depends on the amount of grunt the wielder of the screwdriver uses, and can depend on how many beers consumed/temper/frustration/hurry/stress etc etc the assembler is experiencing at the time.
Hose clips every time for a "proper" job. :)

.. and how many times it's been "nipped up" since. ::)
Spring clips are indeed a much better solution, but they must match the outer diameter of the hose accurately. :y

Just how much does the pipe, hose and clip actually expand, bearing in mind that we are talking about fairly small changes in temperature? It's probably a very small increase, and I suspect that measuring it will be tricky. The differential between the three parts is going to be even smaller. Which makes the 'constant force' more of a theoretical reason rather than an actual practical one. Perhaps someone with some technical engineering expertise could come up with some numbers, Or someone with more time than me actually take some measurements.
I dislike and distrust the sprung clip, and always replace them with quality(usually genuine Jubilee) clips as I've never had a problem with them in use or fitting, which is not something I can claim about the spring type.

Now you've opened a can of worms Nick! :o ;D

disagree strongly here ... ambient temperature at the moment .. around 10 degrees C, operating temperature of the coolant system around 95 degrees C, and also at a differential pressure of around 10 psi IIRC, so quite substantial temperature and pressure changes.
Another thing to consider is that at the higher temperatures the rubber hoses actually "soften" so the "solid" jubilee clip is more likely to "dig in" as well ...

Perhaps, but I've got a Jubilee clips around it, and can tweak it whenever necessary!

I am in the school of preferring Jubilee clips.
As said previously, I always use a thin piece of rubber between the clip and the hose. Provided you don't get all ham fisted and tighten to the point of 'crimping' the hose, you can't go wrong.
Hose clips are in my opinion a once only usage clip. After removal and re-fitting, the 'spring' has lost some of it's potential, and therefore renders it useless. A Jubilee on the other hand can be (when correctly used) used many times.
