The Invention relates to a tracheotomy cannula, comprising a pipe- or tube-shaped element for passing the cannula through a throat or trachea incision into the trachea of a patient whose upper airways are blocked, so as to supply said patient with air through the cannula. A shield is attached to the cannula which rests against the neck of the patient and in so doing determines the position of the cannula or of the end of the cannula in the trachea of the patient. To create a tracheotomy cannula having the above features which can be easily adjusted to fit the anatomical characteristics of a patient and requires no special effort regarding the stock-keeping and adjustment of the tracheotomy cannulas, the invention provides for the shield to be fixably attached to the cannula in various positions in the longitudinal direction of the cannula.
