A pipe joint is disclosed in which a pipe section having a bell end is joined to a pipe section having a spigot end and in which a split locking ring is provided for preventing the sections from separating. The locking ring may be expanded and contracted by means of a pair of lugs attached to the ends of the ring. A U-shaped nut is positioned on one of the lugs and a threaded fastener passes through each of the lugs and the U-shaped nut for engaging a threaded aperture in the nu to draw the lugs together and, an additional threaded nut is positioned on the fastener between the lugs for forcing the lugs apart.

Why it's free to use
- Filed June 6, 1990 and granted May 24, 1994. A Canadian patent filed from October 1, 1989 lasts 20 years from filing, so its term ended June 6, 2010.
- A certificate of supplementary protection adds at most two years for a drug, so even that would have ended by June 6, 2012.
- We check Canadian rights only. A patent in its family in another country could still be in force: check its family on Google Patents.
