The present invention relates to a medicament delivery device having a proximal and an opposing distal end. Said device comprises a medicament container comprising a movable plunger, a neck portion and a delivery member unit a longitudinally extending housing along a longitudinal axis A and having a proximal open end and an opposing distal open end a drive unit arranged at the distal end of the housing and configured to apply a force on the movable plunger a C-shaped tubular body comprising a longitudinally extending slit/gap such that said C-shaped tubular body can be attached to the neck portion of said medicament container forming a container unit wherein said C-shaped tubular body further comprises: inner support means configured to interact with the neck portion and with the delivery member unit of said medicament container such that said medicament container is prevented from being moved in relation to the C-shaped tubular body, after the medicament container is attached to said C-shaped tubular body, and outer support means configured to interact with corresponding support means of the housing such that said C-shaped tubular body is prevented from being moved in relation to the housing after the container unit is arranged within said housing through the distal open end.本發明有關藥物輸送裝置,具有近側端及相反的遠側端。該裝置包括藥物容器,其包括可運動柱塞、頸部、及輸送構件單元;縱向延伸外殼,沿著縱向軸線A及具有近側開放端與相反的遠側開放端;驅動單元,被配置在該外殼之遠側端,且被建構成在該可運動柱塞上施加一力量;C字形管狀本體,包括一縱向延伸裂口/間隙,使得該C字形管狀本體能被附著至形成一容器單元的藥物容器之頸部,其中該C字形管狀本體另包括:內部支撐機件,被建構成與該頸部及與該藥物容器之輸送構件單元互相作用,使得在該藥物容器被附著至該C字形管狀本體之後,該藥物容器被防止關於該C字形管狀本體運動;及外部支撐機件,被建構成與該外殼之對應的支撐機件互相作用,使得在該容器單元經過該遠側開放端被配置在該外殼內之後,該C字形管狀本體被防止關於該外殼運動。10‧‧‧外殼12‧‧‧藥物容器13‧‧‧近側開放端14‧‧‧驅動單元15‧‧‧遠側開放端16‧‧‧C字形管狀本體18‧‧‧頸部22‧‧‧輸送構件單元A‧‧‧縱向軸線
