Abstract
A fluid injection device including a syringe with a body (), a piston (), and a needle () with an injection tip (); a piston rod (); and a sleeve () around the syringe and axially movable between a non-projecting position in which said sleeve () does not cover the injection tip () and a projecting position. The sleeve () urged, while in said non-projecting position, towards its projecting position by a spring (). The sleeve () has an inner portion () extending inside the body, and an outer portion () extending outside the body (), the inner portion () including a radially-deformable tab () snap-fastened in a window () of the body (), blocking the sleeve in its non-projecting position. A hollow member () co-operates, after injection, with the radially-deformable tab (), so that after the fluid is injected, the sleeve is moved automatically towards its projecting position.
