haha, that happened 2 days after I got mine, tied it together with string the first time (never found that plastic peice) and it broke on the first rain a week later. Then I went at it with some rubber bands that you would use for braces. Put about 30 on there, haven't had a problem since... now last time I said "haven't had a problem since," I was towing it the next day, so my door probably won't open tomorrow...
