identifying and obtaining a boiler part

Hi,

I am trying to identify and get a joining pin for a Vokera Compact 24 MTN boiler that secures a water pipe? to a pump? (Grundfos UP type 15-50). How do I get this part. it is very insignicant I am told and can use a substitute piece of wire?
Is there a diagram for the boiler on line?
Thanks for any help given!

do you mean a Cir-clip. U shaped piece of metal. I have just taken a look at the manual on the Vokera Compact and i think the Vokera part number you are after is 2223
