ABSTRACT:
A twist locking connector for a steam humidifier. The steam humidifier includes a tank for heating water to generate steam and a steam tube receiver structure in fluid communication with the tank. The steam tube receiver structure has an opening configured to receive a steam tube, where the opening has a plurality of ramp structures about the opening on a side facing the tank. The steam humidifier also includes a steam tube for transmitting steam from the tank to a duct, the steam tube having a plurality of locking tabs adjacent to an end and a flange adjacent to, but separated by a distance from, the locking tabs. The steam tube is assembled to the steam tube receiver by inserting the steam tube through the opening in the steam tube receiver structure and rotating the steam tube to cause the locking tabs to engage with the ramp structures.
