An air spring connecting device for mounting an air spring strut on a vehicle may include an air spring support bearing having a head bearing receiver, a head bearing having at least one cylindrical outer surface, and a piston rod that is axially guided through the head bearing and is sealed in an airtight manner relative to the head bearing. The head bearing may be positioned in the head bearing receiver of the air spring support bearing positioned coaxially relative to the piston rod. An airtight connection may be formed between the head bearing receiver and the head bearing. A press connection element may be positioned in direct contact with the head bearing receiver and the head bearing. A sealing element may be positioned in a region of the head bearing receiver between the air spring support bearing and the head bearing.
