The needle assembly further includes a shield (50) which is slideably mounted within the main body (10) and an actuator portion (70) which extends outside the main body and is configured for pushing the shield (50) forward manually in use. The shield (50) is slideably moveable between a first position in which the forward portion of the needle (90) projects forwardly of a shield cavity (64), and a second position in which said forward portion of the needle is located within the shield cavity (64). The shield (50) and main body (10) are provided with cooperating features comprising at least one latching element (66) provided on one of the shield (50) or the main body (10) and at least one corresponding engagement feature (44) provided on the other of the shield (50) and the main body. The latching element (66) moves into a latched position as the shield (50) moves into the second position to hold the shield in its second position.
