A puncturing device comprising a band-shaped lancet carrier (2) carrying a plurality of lancets (3), a transport mechanism (6,7,8) for positioning the lancets (3) sequentially in a launch position by moving the band-shaped lancet carrier (2), a lancet drive (4) for accelerating a lancet (3) from the launch position for a puncturing movement, the lancet drive (4) comprising an energy storage (12) for providing energy for the acceleration of the lancet (3), a trigger element (10) for triggering the lancet drive (4), and a housing (5) which comprises at least two housing parts and encloses the band-shaped lancet carrier (2) and the lancet drive (4), the housing (5) having an opening (16), against which a body part is pressed for puncturing by a lancet (3). The puncturing device (1) is adapted for disposable use in that the housing parts were irreversibly connected upon enclosing the band-shaped lancet carrier (2) thereby sealing the band-shaped lancet carrier (2) irremovably in the housing (5).
