    摘要: The syringe is formed according to DIN ISO 11040 and has a syringe barrel (1) with a syringe head (1a) formed on one end and a grip plate (4) formed at the other open end. An elastomeric piston stopper (6) is insertable in this open end, which is movable back and forth and which has a cruciform-cross-sectioned piston rod (7) screwed into it. A stop element, which reduces the interior diameter of the syringe barrel, is provided at the open end of the syringe barrel to perform a back-stop function, i.e. to prevent unintended withdrawal of the piston stopper. For this purpose a plastic part (2) connected to the grip plate (4) is provided with snap catches (3), which snap onto the inner side of the syringe barrel (1). These snap-catches (3) prevent the piston rod (7) from being rotated out of the piston stopper and the piston stopper (6) from being withdrawn from the syringe barrel. At the same time the finger support is enlarged.
