hahaha well in response to upallnight i was up all night rearching, these clamps are called oetiker clamps, apparently not reusable, and whilst not a cost issue have no idea if i can get them out here, they dont come as separate parts from the dealer so you have to buy the whole boot....just concerned about the best way of going about securing the leaking boot until i get hold of a suitable clamp really really don't want to replace the whole boot just cos the clamp on the smaller end of the bellow is not 100% tight...

does anyone know if i can remove it and step up the teeth to the next and last free 'rung' as such? here are pics on how to install and remove
