description A drug delivery device (1), comprising a delivery unit (2) in the form of a disposable single-use part and a base unit (4) in the form of a reusable part for coupling to the delivery unit (2), the delivery unit comprising a housing (7) with a base wall (5) defining a mounting face (25), and a liquid flow system for pumping liquid from a drug vial or cartridge (3) received in the drug delivery device to an outlet of the device for transcutaneous administration of a liquid drug, the base unit including at least a power source and an electronic control system. The housing of the delivery unit is provided with a cartridge check finger (14) that comprises a protuberance (16) mounted on an elastic arm (20), the protuberance arranged to engage a portion (3a) of the drug vial (3) when it is inserted in a cavity (28) of the delivery device, the cartridge check finger comprising a blocking shoulder (17a) arranged to engage a blocking shoulder (17b) on the base unit to prevent full coupling of the delivery unit to the base unit when a drug vial is not inserted in said cavity (28) of the delivery device.
