exhaust to CAT clips/attachments..

[Kiev85]

does anyone know the number of the clips (i can only describe them as "springs" that attach the cat to the exhaust section..?

there seems to be one on each side..thats 4 in total...and can i get them direct from renault..?

my exhaust seems to be blowing and ive sourced it down to a corroded clip...

does anyone know how these work..?? pics or diagram or something...
