Abstract

A syringe assembly has a syringe body adapted to be filled with an injectable liquid and having an annular neck defining an axis and having an axially outwardly open outlet. The neck is adapted to carry a needle. An elastomeric plug engaged axially inward with the neck closes the outlet and a holding ring is fixed to the neck below the plug. A retaining sleeve around the neck is fixed to the holding ring and a cup-shaped safety cap is fixed to the plug and has an end edge confronting the retaining sleeve and spaced axially therefrom. Frangible formations extend from the cap edge to the sleeve.
