A connector (58) for a patient ventilation system is used to connect to a heatable respiratory air tube portion conducting ventilation air from a respiratory air source to a patient and to connect the respirator air tube portion (11) to a patient-air interface. At least one portion (60; 601, 602, 603) of the connector (58) is produced from a thermochromic material, resulting in a connector that reliably indicates a temperature of the heatable respiratory air tube section. |
