A structure for securing the top and bottom cover portions of an air filter includes a wing member secured to the bottom cover portion. The wing member is attached to the cover portion through a post. The wing member has a wedged surface which is selectively moved along a wedged surface on a slot in the upper cover surface. The wedged surfaces cam the wing member to pivot. Once the wing member has moved through the slot, it is biased back and in a direction opposed to the rotation caused by the wedged surfaces. The wing member is thus secured on a surface on the upper cover member adjacent the slot. The wing member thus secures the two cover members in a snap fit connection. To release the snap fit connection, one merely biases the wing member in an opposed direction.
