Abstract: A coded housing of a drug delivery device includes a first housing component having a first connecting end, a second housing component having a second connecting end, an insert on one of the first connecting end or the second connecting end, a receptacle on the other one of the first connecting end or the second connecting end, a fastening element on the insert, a counter fastening element in the receptacle, a mechanical coding on the insert and including a coding feature, and a mechanical counter coding in the receptacle and including a counter coding feature. The mechanical coding is defined by a combination of a position of the coding feature with regard to a longitudinal direction and an extent of the coding feature in one or both of the longitudinal direction or a transverse direction.

Abstract: The present disclosure relates to a housing of a drug delivery device, the housing comprising first and second housing components with first and second connecting ends, and: an insert provided on one of the first connecting end and the second connecting end, a receptacle provided on the other one of the first connecting end and the second connecting end, a fastening element provided on the insert and comprising a snap element, a counter fastening element provided in the receptacle and comprising a counter snap element to engage with the snap element, a mechanical coding provided on the insert and comprising a coding feature, a mechanical counter coding provided in the receptacle, wherein at least one of the fastening element, the counter fastening element, the mechanical coding and the mechanical counter coding comprises a groove.

Abstract: A drug delivery housing device includes a first housing component comprising a first connecting end, and a second housing component comprising a second connecting end. An insert is provided on the first or second connecting end, and a receptacle is provided on the other one of the first and second connecting ends. The insert is insertable into the receptacle for mutually fastening the first and second housing components. A threaded connection mutually connects the first and second connecting ends and includes a helical thread on the insert and a helical counter thread complementary shaped to the helical thread and provided in the receptacle. A rotation lock is configured to impede screwing and/or unscrewing of the first and second housing components. The rotation lock includes a locking structure on the first housing component and a counter locking structure complementary shaped to the locking structure and provided on the second housing component.

Abstract: A coded housing of a drug delivery device includes first and second housing components, respectively including a first and second connecting ends. An insert is provided on the first or second connecting end, and a receptacle is provided on the other one of the first and second connecting ends. The insert is insertable into the receptacle for mutually fastening the first and second housing components. A fastening element is provided on the insert, a counter fastening element complementary shaped to the fastening element is provided in the receptacle, a mechanical coding is provided on the insert and includes a coding feature, and a mechanical counter coding is provided in the receptacle and includes a counter coding feature. The mechanical coding and counter coding are operable to prevent an engagement of the fastening element with the counter fastening element when the mechanical coding does not match the mechanical counter coding.

Abstract: A housing for a drug delivery device includes a first housing component configured to accommodate a cartridge filled with a medicament and including a first connecting end; a second housing component configured to accommodate a drive mechanism of the drug delivery device and including a second connecting end; an insert provided on one of the first connecting end and the second connecting end; a receptacle confined by a sidewall and provided on the other one of the first connecting end and the second connecting end; a fastening element provided on the insert; a counter fastening element complementarily shaped to the fastening element and rotationally supported on the sidewall between a locking position and a release position; a mechanical coding provided on the insert and comprising a coding feature; and a mechanical counter coding provided in the receptacle and comprising a counter coding feature.
