Buggy board problems

[mogs0]

I have just attached a buggyboard to my bugaboo - with great difficulty! I have used a buggyboard on various buggies but I'm sure it's never been as complicated as this!

I am now concerned that I won't be able to get the connectors off. I had a quick try and couldn't budge it so stopped as I need to use it tomorrow and didn't want to risk breaking the connectors.

Anyone else had this problem or have I done it wrong?!

BTW, am disappointed with the fit on the Bugaboo - I don't think it'll be any good if the seat is rear facing but will have a try tomorrow!
