摘要：
The present invention relates an elongated housing for an injection device (10) for delivery of a liquid medicament, the housing comprising: - a tubular-shaped cartridge holder (20) to accommodate a cartridge (50) filled with the medicament and comprising a proximal connecting end (21), - a body (30) to accommodate a drive mechanism (5) operably engageable with a piston (52) of the cartridge (50), wherein the body (30) comprises a distal connecting end (31) connectable to the proximal connecting end (21), - wherein one of the proximal connecting end (21) and the distal connecting end (31) comprises an insert section (22), - wherein the other one of the proximal connecting end (21) and the distal connecting end (31) comprises a receptacle (32) to axially receive the insert section (21), - wherein the insert section (22) comprises at least one fastening element (25) to positively engage with a complementary- shaped fastening element (35) of the receptacle (32) to provide an axial interlock (6) of the cartridge holder (20) and the body (30), - wherein the fastening elements (25, 35) of the insert section (22) and the receptacle (32) comprise at least one pair of a radial protrusion (135) mating with a radial recess (125) provided on an inside wall (36) of the receptacle (32) and on an outside wall (26) of the insert section (22) and - wherein a radial depth (D) of the radial recess (125) is smaller than a thickness of the sidewall of the insert section (22) or a thickness of a sidewall (33) of the receptacle (32).本發明涉及一種用於輸送液體藥劑的注射裝置(10)的細長殼體，該殼體包括：- 管狀的藥筒保持器(20)，其用以接納填充有藥劑的藥筒(50)並且包括近側連接端(21)，- 主體(30)，其用以接納能與藥筒(50)的活塞(52)可操作地接合的驅動機構(5)，其中，主體(30)包括可連接到近側連接端(21)的遠側連接端(31)，- 其中，近側連接端(21)和遠側連接端(31)中的一個連接端包括插入段(22)，- 其中，近側連接端(21)和遠側連接端(31)中的另一個連接端包括用以在軸向上接納插入段(21)的插座(32)，- 其中，插入段(22)包括至少一個緊固元件(25)，該至少一個緊固元件(25)用以與插座(32)的形狀互補的緊固元件(35)強制接合，以提供藥筒保持器(20)和主體(30)的軸向互鎖(6)，- 其中，插入段(22)和插座(32)的緊固元件(25、35)包括至少一對徑向突起(135)，該徑向突起(135)與設置在插座(32)的內壁(36)上以及設置在插入段(22)的外壁(26)上的徑向凹部(125)相配
