Your local mega or hardware store will probably carry replacement lpg bottle connectors. Simply cut off n replace. Make sure your fittings are tight afterwards.
Remember that leaking lpg liquid will "burn" your skin as severely as the flame will. Gloves and goggles are minimum I'd say. And well ventilated too. LPG is heavier than air I think. If I'm correct it'll mean It can accumulate in low areas.
Having said all that I've bought one too and will be trying it out when I get back from this weekend's wallaby trip
