Abstract: The invention is a bandage and an assembly especially designed for proper fixation of an oral, endo-tracheal anaesthesia tube relative to the mouth of a person. The bandage includes a support sheet of a flexible, substantially non-ductile material defining opposite side surfaces and defining contiguous first and second parts. The first part is provided with a coating, at one side surface thereof, of a first adhesive exhibiting the ability of adhering to the skin of a person, and being configured so as to allow the first part to be adhered to the cheek of the person leaving the mouth unobstructed. The second part is provided with a coating, at one side surface thereof, of a second adhesive exhibiting the ability of adhering to the endo-tracheal anaesthesia tube, and being configured so as to allow the second part to be adhered to a segment of the tube extending outwardly from the mouth of the person.
