ABSTRACT:
An injection syringe comprises a cylindrical barrel provided at its open rear end with an initially separate one-piece finger rest and at its forward end with an inserted or permanently fitted cannula or with a conical fitting for the subsequent fixing of a cannula, and a plunger which closes the open rear end of the barrel and which is slidably displaceable inside the barrel by a ram. The barrel of the syringe is formed at its forward end with a head of any desired kind and is provided at its open rear end either in its external or its internal cylindrical surface with one or more annular or similarly shaped recesses or grooves. The peripheral inside or outside surface of the finger rest is formed with a corresponding number of projecting ridges which may be in the form of arcuate ridge segments. These ridges or ridge segments are complementary to the recesses or grooves in the barrel in such a way that when the finger rest is fitted to the barrel the ridges or ridge segments on the finger rest engage the recesses or grooves in the barrel.
