A dose setting limiter for a medical injector. The dose setting limiter comprises of three parts. A first part formed as a shell with a plurality of flanges, which flanges fits retentively over the housing of the medical injector, a second part formed as a dose setting dial and fitted over the rotary dose setting knob of the medical injector and a third part placed between the first part and the second part. The second part is rotational connected to first part while the third part is locked to the first part when the first part is connected to the housing of the medical injector. The maximal allowable dose is preselected with the dose setting limiter disconnected from the housing of the medical injector by rotating the third part until the marker on the third part is placed over the desired maximal allowable dose indication on the scale located on the first part. Afterwards the first part is connected to the housing of the medical injector thereby locking the third part to the first part. When dialling the pointer on the second part clockwise a protrusion provided an the second part will abut another protrusion located on the third part once the preselected desired dose is reached, thereby preventing larger doses from being set.
