Decompression Device and Decompression System

Decompression device comprising:

• a frame element, in which at least one decompression opening is formed, and
• a cover that is fastenable by means of a fastening device to the frame element in order in a first position to close the decompression opening formed in the frame element, wherein the fastening device comprises at least one holding clip and at least one receiving device that is complementary to the holding clip, wherein the holding clip and the receiving device complementary to the holding clip are situated in engagement with one another when the cover is situated in its first position, and wherein the holding clip and the receiving device complementary to the holding clip are adapted to move out of engagement if a predetermined differential pressure acts upon the cover in order to enable the cover to move relative to the frame element into a second position, in which the cover releases the decompression opening formed in the frame element.
