Abstract: An apparatus for an aerosol generating device comprises a first housing member for at least partly defining a chamber for containing a heater arrangement for heating an aerosol generating material; and a second housing member attached to the first housing member via an attachment. The first housing member and the second housing member define therebetween a passageway into the chamber. The passageway is configured to allow an electrical connecting member for connecting to the heater arrangement to extend through the passageway. The apparatus also comprises a sealing arrangement arranged to seal the passageway. The attachment between the first housing member and the second housing member is configured to hold the first housing member and the second housing member in a configuration which causes the sealing arrangement to seal the passageway.

Abstract: A method of assembling an apparatus (1) for heating aerosolisable material to volatilise at least one component of the aerosolisable material to form an aerosol for inhalation by a user, the apparatus having a first proximal end (3) and a second distal end (5), the method comprising the steps of providing a first chassis (19) for supporting a heating arrangement for receiving and heating aerosolisable material, the first chassis (19) or a component supported by the first chassis (19) comprising a first engagement element; providing a first sleeve (11b) to form at least a part of a casing of the apparatus, the first sleeve (11b) comprising a second engagement element; and inserting the first chassis (19) into a cavity of the first sleeve (11b) to cause automatic engagement of the first engagement element and the second engagement element during assembly of the apparatus (1).
