quinny buzz adaptors

hi . I just bought a travel system online second hand and it's not come with any adapters.
I have a carry cot and the maxi cosy car seat.
what do I need to attach it? Do I need to buy 2 separate sets of clips?
Looking online it seems to be one set for the carry cot and another for the car seat but lady I bought it from (who hadn't told me they weren't included ) is saying it's just one set.

If anybody could advise me that would be fab as tempted to just ask for a refund as it's not much of a bargain if I spend loads on clips

Its just the one set for both. I think you can order them as spare/replacement parts in a mothercare store.
