Abstract
An outer barrel for a syringe having a needle hub mounted on a front end of an inner barrel has at least two halves combined with each other. Each half has a pawl formed at a rear end of the inner surface of the half and selectively engaging with the needle hub. When the inner barrel is pulled out from the outer barrel, the needle hub with a needle is kept inside the outer barrel after the syringe is retracted from the outer barrel. The at least two halves are able to cover syringes with different sizes provided from different syringe manufacturers, so that the outer barrel is versatile in use.
