The present invention concerns a device having a guide catheter for the introduction of a tracheal cannula into a tracheostoma. To provide a device for introducing a tracheal cannula into a tracheostoma, which prevents injury by the distal end face of the cannula and which is suitable for use in relation to highly flexible cannulas, in relation to cannulas of tight inside diameter and/or of large wall thickness, it is proposed in accordance with the invention that the guide catheter has a shield which is mounted in the proximity of the distal end of the guide catheter and which comprises a flexible material and which is substantially in the form of a distally directed conical tip, wherein the tube of the guide catheter passes through the axis of said tip, with a base outside diameter which in a first state corresponds at least to the outside diameter of the tracheal cannula and in a second state by deformation is smaller than the inside diameter of the tracheal cannula and is thus retractable through the tracheal cannula.
