The invention relates to a tracheal cannula (1), in particular a tracheostomy cannula or an endotracheal tube, with a cannula tube (2) which is made of plastic and has a proximal end (2a) with a proximal opening (2b), a distal end (2c) with a distal opening (2d), and at least one separate line (4) which extends in the axial direction of the cannula tube (2). The aim of the invention is to provide an easily producible tracheal cannula with at least one integrated line. According to the invention this is achieved in that the cannula tube (2) has a region with a reduced wall thickness over a part of the tube circumference on the exterior of the tube, said region defining a recess (2e) which extends in the axial direction for at least partly receiving a suitably shaped profiled element (3). The profiled element (3) is made of a plastic which is harder than the plastic of the cannula tube (2), and the line (4) is formed between the mutually facing surfaces of the profiled element (3) and the recess.
