  • Publication number: 20130170904
    Abstract: A composed element includes at least two panel-shaped elements, such as a locking tongue and groove connection, that are arranged to be coupled to each other at an angle, either directly or indirectly by means of an intermediate piece. The connection includes, at least at one of the panel-shaped elements, a tongue or groove, cooperable with a groove or tongue provided on the other panel-shaped element or on the intermediate piece. The tongue includes a split tongue, with at least a first part and a second part, and a slit located therebetween. A locking part is located at the outer side of at least said first part wherein the slit, seen in cross-section of the tongue, defines at least one side, the course of which, seen in cross-section, deviates from the main direction belonging to the tongue.
