Abstract

1396299 Pipe couplings; valves D J WALTERS 27 July 1972 [3 Aug 1971] 36478/71 Headings F2G and F2V In a valve connector for a pump, such as a foot pump for motor vehicle tyres, a plastics spigot end 22 of a ball recess is formed with a slot 34, the edges of which are arranged to spring apart and together again, as ball 36 is inserted into the recess. The ball 36 may be of steel or plastics. An integral screw-threaded spigot portion (18, Fig. 2, not shown) is provided.
