The present invention deals with a simple retractable syringe comprising of of a barrel having a needle mount with a needle placed within the distal end of the barrel in a sealingly slidable manner.. The needle mount is made up of a flexible and deformable material with a hollow cylindrical base structure. A plunger is having an inverted cone shape tip is slidably disposed within the syringe barrel The cone shape tip of the plunger can tightly engage with the hollow cylindrical base structure of the needle mount on contact with slight pressure-for enabling retraction of the needle mount with the attached needle into the barrel after the injection process is completed.
