Claim Text:
1. An injection device comprising: a housing having a longitudinal axis, a dose setting member being operable by a user to set a desired dose to be injected, the desired dose thereby being a set dose, a piston rod being adapted to cooperate with a piston so as to cause the set dose to be injected from an ampoule, and a dose delivering mechanism being adapted to operate the piston rod in such a way that the set dose is injected by means of a mechanically biased mechanism comprising at least one spring, the dose delivering mechanism further being adapted to provide a distinct audible feedback signal to a user only at the end of injection of the set dose, wherein first and second parts of the injection device are adapted to perform a relative rotational movement around a longitudinal axis with respect to each other during injection of a dose, and wherein said relative rotational movement causes at least the first and the second parts of the injection device to abut or engage, said abutment or engagement causing the audible feedback signal to be generated.
