A drug delivery device is provided comprising a cartridge holder (2) comprising at least one guide track (12), and a body (3) comprising at least one interaction member (13) adapted and arranged to mechanically cooperate with the at least one guide track. The guide track (12) comprises a first section (12A) and a second section (12B), wherein the path which is defined by the first section (12A) encloses an angle with the longitudinal axis (14) of the device, wherein the angle which is enclosed by the path defined by the first section (12A) with the longitudinal axis (14) is smaller than the angle which is enclosed by the path defined by the second section (12B) with the longitudinal axis (14), wherein, for connecting the cartridge holder (2) to the body (3), the interaction member (13) is configured to mechanically cooperate with the first section (12A) such that the cartridge holder (2) is axially moved and rotated with respect to the body (3), and the interaction member (13) is configured to mechanically cooperate with the second section (12B) such that the cartridge holder (2) is rotated with respect to the body (3), whereby an axial movement of the cartridge holder (2) with respect to the body (3) is prevented. Furthermore, a cartridge holder for a drug delivery device is provided.提供一種藥物傳送裝置，其係包含：包含至少一導槽(12)之一匣支架(2)，以及包含經適合及配置成可與該至少一導槽機械合作之至少一互動構件(13)的一主體(3)。該導槽(12)包含第一區段(12A)與第二區段(12B)，其中由該第一區段(12A)定義之路徑與該裝置之縱軸(14)有一夾角，其中由該第一區段(12A)定義之路徑與該縱軸(14)的夾角小於由該第二區段(12B)定義之路徑與該縱軸(14)的夾角，其中，為了使該匣支架(2)連接至該主體(3)，該互動構件(13)經組態成可與該第一區段(12A)機械合作使得該匣支架(2)相對於該主體(3)可軸向運動及旋轉，以及該互動構件(13)經組態成可與該第二區段(12B)機械合作使得該匣支架(2)相對於該主體(3)可旋轉，藉此防止該匣支架(2)相對於該主體(3)軸向運動。此外，提供一種用於藥物傳送裝置的匣支架。
