1. A drug delivery device comprising a module adapted to accommodate a reservoir configured for holding a liquid drug, wherein the module comprises:
a first housing portion, the first housing portion comprising a bearing element configured for supporting a neck or head portion at a first end of the reservoir; and
a second housing portion, the second housing portion comprising an elastic contact element configured for supporting a second end of the reservoir opposite the first end of the reservoir,
wherein the first and second housing portions are configured to be connected to one another in an assembled state in which the first and second housing portions form a cavity for accommodating the reservoir,
wherein the bearing element and the elastic contact element each define a limiting structure of the cavity in a longitudinal direction of the cavity, which together are configured to secure or hold the reservoir free of play within the cavity,
wherein the elastic contact element is injection molded onto a surface of a body of the second housing portion, and wherein the elastic contact element is made from a material that differs from a material from which the body is made.
