A connector 20 for connecting a vacuum cleaner 22 to an end of a hose 24 comprises a threaded body that receives a threaded shell 14. When the shell 14 is fully tightened to the outside of the body, the shell distorts a specially preformed seal 16. The seal 16 grips the outside of the hose 24 to form an airtight seal. The same connector can be used for somewhat different dimensioned hoses by using different seals 16.

Why it's free to use
- Filed July 10, 1998. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended July 10, 2018.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by July 10, 2020.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
