John, there is an aftermarket clip to deal with this. It fits on the outside of the door. If you go into any large dealer in RVs you should find the catalogue from which the dealers order their parts. I'm told that there are only two or three main catalogues of this type. You should find the clip in any of these. I'm 4000 miles from my trailer and catalogue, so I can't be more specific. If you want a catalogue, and I find mine indespensible, you can buy one from Sanders RV of Alachua, FL, tel. 800 541 6439 and 386 462 3039 for a few dollars, or one is free with orders over about $30 or thereabouts. Someone on the forum may be able to look it up in the catalogue to give you more details. Good hunting. Nick.
