Abstract An attachment device particularly designed to support cabinets, mirrors, shelves and similar elements which are removably mounted on at least two strips arranged horizontally on the wall in parallel and opposite relationship. Means on the strips cooperate with matching means on the element or on members which may be connected to the element. A tongue on the element or the connecting members may be inserted in a groove in one, of the strips or vice versa. The other strip is provided with a groove and the element or connecting members, for cooperation with the latter strip, is provided with grooves or controllable snap means, said grooves or snap means assuming a position opposite the groove and close to the latter when the element is applied against the wall. A number of elements can be mounted along the strips and be secured in the desired position by allowing the snap means to slide into the groove in the other strip.
