Tube for a respirator system

A ventilation tube system comprising:

• an exhalation tube;
• an inhalation tube upstream of a respiratory humidifier;
• an inhalation tube downstream of the respiratory humidifier, such downstream inhalation tube including:
• a first section comprising a heating wire, an electrical line, and a first connector and a second connector;
• and
• a second section comprising a heating wire extending over at least a certain portion of its length, an electrical line extending over at least a certain portion of its length, and a first connector and a second connector, the second section including a temperature sensor;
• electrical and pneumatic connection of the first section with the second section via the connection of the second connector of the first section being achievable by either one of two different alternative configurations, including (a) a first configuration in which the second connector of the first section is connected to the first connector of the second section so that the second section is heatable, or (b) a second configuration in which the second connector of the first section is connected to the second connector of the second section so that the second section is substantially not heatable.
