Abstract
The invention relates to a tongue connection, in particular for fixing an air vent on a wall in a passenger compartment, on a basic body which is to be arranged in a releasable manner on a border of a wall opening by way of at least two tongues which project from the basic body, the tongues engaging, along the opening border, in the opening and restricting movement of the body in the direction of the opening plane. There is provided on at least one tongue a (radial) protrusion which projects outward in the direction of the opening border, cuts into the opening border when the basic body is installed on the wall, and prevents movement of the basic body in the opening plane by producing a form fit in relation to the opening border.
