Abstract: A protective device for a sanitary fitting contains a covering, which during installation steps is mounted such that outlets of the fitting are sealed in pressure-resistant manner and/or are interconnected. This sealed covering is connected by separable means to a cylindrical skirt, which surrounds the fitting and/or the fitting part. After the installer tests the house plumbing and completes the wall surface, the covering is removed again from the sanitary fitting or the part thereof. As desired, it is also possible to remove the skirt or leave it in the wall. For this purpose the skirt is attached to the sealing part of the covering by easily separated ridges.
