Beschreibung
Zusammenfassung:	A pressure relief cover for reducing pressure generated in a cell-like cavity, such as a battery cell, having a cover part which holds a seal for sealing a housing opening up to a predetermined cell pressure and having a holding device to fasten it to the housing opening. An advantageous type of mounting with a reliable function is achieved in that the holding device has a spring clip attached to the underside of the cover part at the housing opening with a plurality of radially outwardly directed spring tongues which at their ends are provided with spring sections which are resiliently movable backward in the radial direction upon pressing the cover part onto the housing opening through the opening edge and snap back under a wall area around the opening edge after penetrating the housing opening.
