When two tubes - the endotracheal (15) and the oropharyngeal (guedal) (10) tubes are placed in the pharynx, the other (guedal) tube lies at right angles under the pre-set spot (19) in the imagined vertical plane of symmetry of the patient's body on the hard gum on the tongue's (55)top side(54). The at least two guides (2,7) holding the endotracheal tube on the extension-piece are positioned to the left and right and extend to the longitudinal direction of the connecting piece.
