inadequate deluxe camping vario

I bought this regulator for the deluxe and vario such was my surprise at the opening of the barbecue where the original hose supplied with the barbecue has two side screwed. Impossible unless this regulator is cut pipe at the screw. If you seek an expansion for the vario deluxe is the assembly EN 417 for you and especially not this one. I atend my refund for this product.
