The syringe (100) has a nut part (400) comprising retaining surfaces (420a, 420b), which are form-fittingly connected with counter-retaining surfaces (320a, 320b) of a piston end (360) such that the nut part is not axially displaced in relation to a syringe body against discharge direction. The retaining surfaces and the counter-retaining surfaces are form-fittingly connected such that the retaining surfaces and the counter-retaining surfaces are not relatively movable, where the relative movement is directed perpendicularly to a sliding direction.
