A cartridge holder (1) suitable for an injection device is proposed. The injection device is adapted to administer a dose of a medicament to a patient. The cartridge holder (1) is adapted to receive a medical cartridge (2) containing the dose of the medicament. The cartridge holder (1) comprises an annular collar (1.2) with a first set (S1) of first detents (1.2.1) arranged around a circumference of the annular collar (1.2). Each first detent (1.2.1) projects from an inner surface of the annular collar (1.2) in a radial inward direction. The first detent (1.2.1) is adapted to engage a corresponding second detent (2.2) of the medical cartridge (2) to mount the medical cartridge (2) to the cartridge holder (1). The first detent (1.2.1) is resiliently arranged and/or supported so as to provide a unidirectional torque limiter that restricts a maximal torque between the cartridge holder (1) and the medical cartridge (2) in a first rotational direction (R1).
