The present invention provides a parenteral device comprising a body having a forward end and a rearward end, the forward end being capable of receiving a hollow retractable needle therein so as to project therefrom, the retractable needle being slidable relative to the body, the body also including a chamber capable of receiving parenteral fluid capable of being reduced in volume to expel fluid contained therein, wherein: the needle is capable of being manually retracted within the body such that the chamber reduces in volume to expel fluid contained therein and such mannerthat the needle is retracted to be wholly contained within the body; the retractable needle is mounted in a plug, the plug being configured so as to be slidable relative thereto; the chamber is located rearwardly of the plug such that the needle projects through the plug to provide fluid communication with the chamber at the rear thereof and the hollow interior of the needle; a stopping means is provided to define the rear extent of the movement of the plug and also to define the rear end of the chamber.
