1. An aerosol-generating article comprising:
a plurality of elements assembled in the form of a rod having a mouth end and a distal end upstream from the mouth end, the plurality of elements comprising an aerosol-forming substrate with an elongate susceptor arranged longitudinally within the aerosol-forming substrate, wherein a plug element comprising a hollow tube is located upstream of and adjacent the aerosol-forming substrate and the elongate susceptor within the rod to prevent the elongate susceptor from dislodging from the aerosol-forming substrate, the plug element preventing direct physical contact with a distal end of the elongate susceptor arranged longitudinally within the aerosol-forming substrate, wherein an inner diameter of the hollow tube is smaller than a width of the elongate susceptor, and wherein the plug element has a resistance to draw (RTD) that does not exceed 30 mm WG.
