Habitation lock

[Tedster]

Is there a habitation lock that would go over the existing lock on my Elddis Accordo 105?
Thanks in advance

This is what I have on my van (was on when I bought it). There is a little lever you pull down (located under the top part of the arm) and this allows the arm to swing out to the middle and then across the door. You can lock the lever to stop it moving and so effectively becomes a secondary locking device for the door. I actually prefer to use this as the door lock rather than the actual door lock as I'd say a good pull on the door and the 'caravan style' lock would give way.

With regards to information about it, sorry I can't help, but at least you have an idea.
