I am looking for the retaining clip for the bottom left connection to the radiator (viewed from front of car) for a 1998 2.0 petrol auto 406 GLX.
Realise this is a rather niche requirement...

Have managed to source radiator and hose after much waiting and searching but some bright spark apparently threw away the retaining clip that came with the radiator.
Have the car all ready to fill with coolant and finally use but dare not run it up without the union held together properly.
Does anyone know where one can be obtained, or a part number etc etc? Anything off another car that can be "adapted"... Any experience of this problem and have an alternative solution...?
Have called my local Peugeot dealer who have been very sympathetic but they say the clip was only supplied with radiator and not sold separately.
Happy to expand on detail for anyone interested.
Picture attached if it helps explain what is required.
(FYI: I am the happy and content owner of a 406 90HDI Rapier estate which has served me faultlessly for 10 plus years.
I was offered the one referred to in this post for minimal money and it is very low mileage and I believe worth perservering with.
Realise others will think differently but that is not the subject of this post.)
