Abstract
A method of making a one-piece, rigid thermoplastics body for a discrete, releasable push-in tube coupling device of the collet type comprises initially injection moulding the body about one or more rigid cores. Each rigid core is then withdrawn axially while the moulding is still in a plastic state whereby the outer, narrower bore portions of the body expand radially. The expanded portions are then radially contracted back to their as-moulded configuration using a jaw-like tool and finally the body is allowed to cool.
