摘要

Method of assembling a glass tube and thermoplastic resin finger-grip and nose-forming sleeve syringe body assembly in which the finger-grip sleeve and the nose-forming sleeve are each cam-stretched onto and frictionally retained on respective opposite ends of a glass tube, which is a section of die-formed glass tubing. Increase in latitude of operable interference fit and stretch is effected by assembling the finger-grip and nose-forming sleeves onto the glass tube while the sleeves are in a heated condition.
