When I was on an Aire recently, another Brit' (non-Funster) Motorhomer filled up with fresh water using a hose with an unusual tap connector on the end. The wall-mounted tap was a push-button domestic type with a really short 'spout'. This guy had an adaptor which looked like a small black foam doughnut - terminating in a standard hozelock male spigot. It had no jubilee clip and as if by magic, just held firm on the short tap. Couldn't quiz him too much as it was persisting down with rain and he was hot to trot. He just said that he got 'one of the last few going' but didn't say from where. I've scoured various sites, but can't find one. Anyone seen one?
