摘要：
Disclosed is a drug delivery device for administering a predefined dose of a medicament from a cartridge. That has a reliable mechanical inter-connection between the cartridge holder and the device body. The drug delivery device comprises a housing that comprises a body to accommodate a drive mechanism, a cartridge holder to accommodate a cartridge having a piston slidably disposed therein in an axial direction (z), and an interconnection (59) between cartridge holder and body. The interconnection has at least one displaceable or resiliently deformable latch element (68) to mate with a corresponding bearing (54), wherein the latch element (68) is displaceable or deformable in a direction (z, w) extending substantially parallel to a circumferential side wall (52, 65) of the body or cartridge holder. The cartridge holder and body comprise an insert portion and a corresponding receptacle portion for establishing an at least partially interleaved interconnection of cartridge holder and body. The receptacle portion comprises the at least one bearing extending in a lateral plane (x, y) with respect to a tubular shape of cartridge holder and/or body and extending radially inwardly from an inside facing side wall section of the receptacle. The bearing comprises at least one axial through opening to receive the latch element.
