Simply cut off the hose at the damaged part, and put on this part, using neutral curing, window and gutter silicon as a sealant. NOT MANY LEFT!!
This was the Original Nilfisk and Tellus method of joining the 32mm hose and the bent tube via a rubber muff for extreme flexibility reducing the stress on the operator's wrist.
The rubber muff allows for easy removal of the bent tube for removing blockages or for joining vacuum hose to portable equipment, without loosing effective suction.
To easily dis-assemble the muff, compress the joint in one hand and slip a ring off with the other hand.
Once you've done it a few time, you'll get the knack!
