A coupling for a flexible soft hose for example for a foam supply duct of a car wash includes a helical spring wrapped around the end of the hose with a spring on the end of the hose inserted into a sleeve member and abutting a shoulder within the sleeve member. A threaded insert member is then engaged through the sleeve member to the inside of the hose thus squeezing the hose outwardly to engage the inside surface of the spring. A swivel coupling can be provided on the male insert member using a replaceable O-ring and clip ring mounting.

Why it's free to use
- Filed September 10, 1993. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended September 10, 2013.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by September 10, 2015.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
