Broken catch on door under bench seat Duetto

The small catch under the bench seat to which the front drop down door (piano hinge) fastens has broken. It is a 2010 Duetto and it looks as if it may have broken before and been glued!  (Previous owner had it for 6years). The push button part is fine and I am now having to hold the door upby tying string round the button and fastening it to the bed pull out handle.  A/S say they have been replaced with something which is longer which will have to be cut down.  They sent a photo which looks totally different to what has broken and I am wondering if the previous owner just found something that would do?

Has anyone had a similar mishap and if so how did they overcome it? 

Many thanks.

Have a look on O'Leary's website.

If they haven't got one, nobody has!!  [You must be registered and logged in to see this link.]

Is the fastening the same as overhead cupboards?

That's what I thought it was like. W4 do them, you'll find them on the bits and pieces stands at caravan dealers.

Many thanks for all your help.  The O'Leary site looks like one to remember!   
I need to check the size but it looks as if they have just what I want.  
I think this forum is brilliant.  I am learning so much by reading threads.  Thank you.
