1. A device for holding a tracheostoma device over a tracheostoma of a patient comprising:

  • a tubular portion defining a passage having a distal and a proximal opening, the tubular portion being configured to receive the tracheostoma device at the distal opening thereof and hold the tracheostoma device over the tracheostoma;

    a flange extending radially from and about a circumference of said tubular portion, said flange forming a conical shape that is inclined proximally towards a central axis of said passage, said flange having a proximal side configured to face the tracheostoma of the patient, and a distal side configured to face outwardly from the patient, at least a part of said proximal side comprising a skin adhesive,said flange having a higher moment of resistance in a lower/upper direction from said tubular portion than in a transverse direction from said tubular portion by having a higher moment of resistance in the lower/upper direction than in the transverse direction for at least a part of said flange;

    wherein said higher moment of resistance in the lower/upper direction is obtained by a plurality of reinforcements on the distal side of the flange and extending from the circumference of said tubular portion, such that at least one of the reinforcements extends tangentially and in a lower direction from said tubular portion and at least another one of the reinforcements extends tangentially and in an upper direction from said tubular portion, so as to provide the device with an improved resistance to flipping over in the lower/upper direction.
