Henry Hoover spare part?

MoneySavingExpert.com has just posted the following message with the title Henry Hoover spare part?.

I've had a Henry 'hound' for about the last 6 years or so, but I came to use it yesterday and the hose part keeps coming out of the hoover, it looks like a part of the green tube has broken off (see photo). It's very annoying as you cannot pull the hoover along when using it as it keeps coming out. I tried super glueing it in, but is didn't work and has come out again. Does anyone know if it's possible to get this part as a spare, I don't even know what the part is called. Image: http://img299.imageshack.us/img299/7497/p1000282p.jpg
