Claim 14:
15. 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, and
wherein the dose selector only moves in a proximal direction to start a dose delivery when the second protrusion is aligned with a cut-out in the radial projecting rib.
