A breathing device for placing on a tracheostoma of a patient comprising:

• a cylindrical housing;
• an annular housing support;
• a plane, movable, flexible flat part with sealing and adhesive functions and central hole;
• a filter or a speech valve;
• and
• a cover plate;
• and wherein the housing contains the filter or the speech valve and is provided with a proximal opening that is detachably connected to the tracheostoma thus communicating with it, and a distal opening positioned at an opening side opposite to the proximal opening and protruding from the tracheostoma to the outside, and the housing engages with the proximal opening into the housing support in a sealed and detachable manner and is mounted via the flat part above the hole and the tracheostoma, wherein
• the housing comprises, in the wall thereof, recesses for introducing and extracting respiratory air, and on the proximal opening thereof, an outer edge comprises at least three edge segments which are on the outer wall and at least three edge recesses, said housing carries the cover plate at the distal opening of the housing and surrounds the filter or the speech valve, and holding rods hold the filter on the proximal opening;
• the housing support comprises an annular flange having at least three inner wall support projections and an annular outer wall base and said support projections are provided with a receiving area;
• the housing support supports the housing with filter or speech valve by a configuration in which the edge segments can be precisely engaged into the support projections by rotating the housing in the housing support and can be locked in place in the receiving areas;
• and
• the housing support is joined to the flat part in a fixed and sealed manner.
