Abstract
A method and apparatus for producing plastic parts with a resilient projection, such as connectors for corrugated tubing. The method comprises the steps of flowing plastic material on a core provided with a recess to mould the resilient projection, camming the resilient projection out of the recess, after the mass of plastic material is solidified and extracting the solidified part from the core. The invention also extends to a novel connector for corrugated tubing.
