Abstract

An injection device for delivering a liquid composition, including a generally elongated housing, arranged to hold an exchangeable cartridge containing the liquid composition. The housing includes a drive device, and a plunger rod connected with the drive device and connected to a plunger within the cartridge, when the cartridge is held at the housing, for driving the plunger within the cartridge. The plunger includes a rod connector connected with a front end portion of the plunger rod. The rod connector comprises a rod stop portion, wherein there is a longitudinal play between the plunger rod on one hand and the entrance opening and the rod stop portion on the other hand, thereby enabling the front end portion to move back and forth between the entrance opening and the rod stop portion without moving the plunger.
