How can I join 2 single buggies?

Thank you to all that replied. I`ve just tried the Princelionheart.com and as you say, they have them there, very similar to the original McLaren clips, so thank you for that. Oh don`t worry Aka not at all dangerous I used my original set for years with my two boisterous little boys with no mishaps. I think McLaren just want parents/grandparents to purchase the twin buggy instead of just having to buy one additional buggy plus clips when twins come along.

I'm on a mission here (bored)

They can be found with a quick google including e-bay

Does sound risky.
But if you want to do it, what about two or three leather straps that buckle up tight to the frames. If you can find them. Or have them made.

I think that may be why McLaren have withdrawn them.

Sounds potentially dangerous.

Have you tried looking on line at various sites ?
