Claim 17:
18. A dose setting mechanism comprising:
a dose knob;
a dose selector;
a radial projecting rib positioned circumferentially on an inside surface of the dose selector; and
a snap element comprising a first protrusion and a second protrusion,
wherein engagement of the second protrusion with the radial projecting rib prevents axial movement of the dose selector in a distal direction, the distal direction being a direction toward an end of the dose setting mechanism that is furthest from an injection site of a patient,
wherein the radial projecting rib comprises a plurality of cut-outs that are axially aligned to a plurality of dose stops positioned on an inside surface of the dose selector, where each dose stop corresponds to one of a finite set of predetermined fix dose settings, and
wherein the dose knob can only move axially relative to the snap element, when the first protrusion is engaged with one of the dose stops of the dose selector.
