    摘要： A drug delivery device for dispensing of a dose of a medicinal product is presented comprising a first housing component having a receptacle being oval- or elliptically shaped in radial cross section and being adapted to at least partially receive an insert portion of a second housing component being at least partially insertable into said first housing component along an axial direction, wherein the insert portion is oval- or elliptically shaped in radial cross section. The outside dimension or an at least one outside diameter of the insert portion is at least in sections larger than a corresponding inner dimension or an at least one inner diameter of the receptacle and wherein the insert portion and the receptacle are adapted to generate a radially acting mutual clamping of first and second housing components in a pre-fixing assembly configuration.
