Gas BBQ Connector? Help!!

Hello again. I have a Compass Omega 505 with the external gas BBQ connection / flap.

I am a noddy caravanner and welcome advice. I recently purchased a basic ASDA gas bbq that came with standard regulator etc and pipe to unit. When ive checked the caravan they look totally different connections?

Can anyone advise on the sort of thing i am looking for? or am i missing something?

Got a bbq booked next weekend so need a swift solution!! Assume it also just fed from van gas?

Thanks in advance
