Abstract: A piercing system for use in aerosol-generating devices may be used to form one or more openings in a shisha cartridge. The piercing system includes a piercing assembly and stem pipe. The stem pipe may be incorporated as part of an aerosol-generating device. The piercing assembly comprises a body with a through opening. The opening may be coaxial with the hollow tube of the stem pipe. The piercing assembly comprises a plurality of piercing elements at its upstream end. The piercing elements are configured for piercing a cartridge. The piercing assembly may be operated by placing a cartridge onto the piercing assembly and pressing down on the cartridge.
