A second engagement member is arranged at the barrel to engage with said grooved surface of the first engagement member, wherein the first engagement member is arranged to move relative to the second engagement member, such that feedback is given to a user as the plunger rod is moved relative to the barrel for driving said plunger. The first engagement member is arranged at said plunger rod with a predetermined play there between.
