Abstract

A syringe assembly has a tubular syringe body centered on and extending along an axis and formed at a rear end with a radially outwardly projecting rim. A finger brace of limitedly elastically deformable material is formed with an end plate bearing axially forward on the rear end and formed with a central hole. A tube projects axially forward from the hole of the plate into the body at the rear syringe end, and a collar extends axially forward form the plate outside the tube and is formed with a plurality of angularly spaced and radially inwardly projecting teeth engaged under the rim. The plate is also formed adjacent each of the teeth with an axially throughgoing and angularly elongated slot defining a radially elastically deflectable side portion carrying the respective tooth.
