A filter device, for a ventilation system of a motor vehicle, comprising:
- a filter housing defining a space inside the housing,
- a filter element configured to be inserted into the space,
- a lid for closing the space, wherein the lid is releasably fastened to the filter housing via a bayonet closure, such that the lid can be axially inserted into a lid receptacle formed on the filter housing and can be rotated in the inserted state between an unlocking position and a locking position, and
- a securing device for securing the lid into the locking position and preventing the lid from being rotated into the unlocking position, wherein the securing device includes a latching hook which is resilient in the radial direction and which, during the rotation of the lid from the unlocking position to the locking position, moves in the circumferential direction relative to an obstacle, runs over the obstacle to reach the locking position and engages behind the obstacle in a form-fitting manner when the locking position is reached.
