A needle assembly and cylindrical cover housing which are usable with a conventional hypodermic syringe. The needle assembly has a circular mount on it with catch slots and slanted surfaces. The cover housing has inward projections which are flexible so that the hypodermic syringe can be received in the cover housing and also for frictionally engaging in the catch slots so as to secure the needle assembly completely in the cover housing after usage.
