Abstract

A syringe for drug injection from a cartridge (26) has a hand-and- thumb operated plunger (4) that slides through a finger-hold (3) into a tubular body (1) which is attached to the finger-hold (3) by a bayonet connection between pins (17) of the finger-hold (3) and L-shape slots (15) of the tubular body (1). The bayonet connection is established by twisting the body (1) relative to the finger-hold (3) and this also engages tags (16) of the body (1) with slots (18) of the finger-hold (3) to enhance the attachment. A needle-guard sleeve (12) slides on the tubular body (1) between a retracted condition in which it is clear of the distal end (8) of the body (1) for needle-attachment, and a pre-use condition in which the needle (32) is shielded. After injection the sleeve (12) is pushed further forward over the needle (32) into a post- use condition, from which return to the earlier conditions is blocked.
