We use the rubber washers you find on german beer bottles when they have the traditional porcelain-lock. They are made of a steady wire and porcelain and use a rubber washer to seal everyting airtight.
Just use the normal strap holder, get on the strap and mount one of this tubber washers over it. No more chance to get out. Just bombproof.
Seen that done before, just never seen/found any of the washers that are suitable
