[0062] Figure 6 shows a wall box 100 inserted into a wall 1000 with a wall sleeve 1 and a pipe 4 connected to the wall sleeve 1. As particularly shown in Figure 6 As can be seen above, no screw connections of the wall sleeve 1 with the wall 1000 are necessary in order to fix the wall sleeve 1 and / or the wall box 100 in the wall 1000. Figure 6Below is another view of a wall box 100 with a connecting element 13 connected to the wall sleeve 1. The connecting element 13 can be a cross-section adapter. The cross-section adapter can, for example, change a square and / or flat cross-section to a round cross-section.

[0063] The installation of a wall box can include the following steps: 1. Measure the wall thickness of a wall 1000 and determine the required pipe length. The required pipe length can be calculated, for example, from the difference between the measured wall thickness and the insertion depth of the pipe holder 3. For example, if the wall is 70 cm thick and the pipe holder 3 of the wall sleeve 1 has an insertion depth of 40 cm, the pipe length can essentially be 30 cm. In some embodiments, the pipe length can be chosen to be somewhat longer so that the pipe 4 can protrude from the side of the wall 1000 facing away from the wall sleeve 1. 2. Cut the pipe 4 to the specific pipe length. 3. Push the pipe 4 into the pipe holder 3. 4. Push the wall sleeve 1 and pipe 4 into a through hole 101 in the wall. For example, the wall sleeve 1 and pipe 4 can be inserted from the inside or from the direction of an inner side 1003 or a side 1003 facing the inside of the wall 1000. In some cases, force is applied using a rubber hammer.5. If necessary, interrupt assembly and wait until, for example, a facade or interior surface is finished. To protect against dirt, polystyrene covers can be inserted on both sides, e.g. on or in the wall sleeve 1 and / or the pipe end facing away from the wall sleeve 1. 6. If necessary, position the insulation device 103 in the pipe 4. To do this, for example, the insulation device 103 can be pushed from the inside side 1003 of the wall 1000 through the wall sleeve 1 into the pipe 4. 7. Insulation between pipe 4 and wall 1000, e.g. from the outside or outside. 8. Fasten the external blind 101 to the pipe end facing away from the wall sleeve 1.

[0064] Advantageously, assembly can be carried out without tools. This allows for very rapid installation. The wall sleeve 1 and / or the pipe 4 can be firmly connected to and / or with the wall 1000 by the clamping rib 6. Furthermore, waiting and drying times during assembly can be eliminated, as the pipe 4 can be glued in place later.

[0065] Installation up to wall 1000 can be performed, for example, by a kitchen fitter, while the blind 101 can be installed later by the customer or owner after the facade is completed. Until final completion, the wall sleeve 1 and / or the pipe 4 can be covered by a cover, e.g., a Styrofoam cover.

[0066] Wall sleeve 1 and pipe 4 can be connected to each other in an airtight manner. Furthermore, small additional installation heights can be achieved by inserting molded parts and / or connecting elements 13. If the wall sleeve 1 is made of or comprises LPDE, it can be lightweight and flexible, thus facilitating installation. List of reference symbols
