Abstract
A drug delivery device includes an inner body adapted to receive a pre-filled syringe with an injection needle, one or more flexible arms on the inner body extending in a distal direction, and one or more support members slidably arranged to operatively outwardly support the flexible arms. The flexible arms have respective inwardly directed protrusions adapted to engage a neck of the syringe. When the support member is in a distal position, it does not support the flexible arms. When the support member is in a proximal position, the support member supports the flexible arms and prevents them from being outwardly deflected.
