An injection device includes a housing, a dosing member held so as to be rotatable and fixed in the housing and an injection sleeve held so as to be rotationally fixed in relation to the housing and displaceable therein. A latching unit of the injection device is configured to act between two components thereof which, during setting of an amount of injection fluid to be dispensed, move relative to one another. A set amount of injection fluid is unequivocally assigned to each relative position of the two components.
