Building element system

Building element system comprising:

• first and second building elements,
• wherein, for a releasable connection of a first building element to a second building element, a first connecting means is provided on the first building element and a second connecting means is provided on the second building element, which first and second connecting means can be latched together,
• wherein the first connecting means is rotationally symmetric and comprises a circular bore defining a complete circle, the first connecting means being situated on a building element side of the first building element and having at least two latching projections which jut inward, each of the latching projections forming chord in the circular bore, each respective chord defining a straight line segment between two points on the complete circle of the circular bore, the line segment being located entirely within the complete circle of the circular bore, and
• the second connecting means is an annular bead configured on a projection situated on a building element side of the second building element wherein, when the first and second connecting means latch together, the projection of the second connecting means extends into the circular bore of the first connecting means, and the annular bead on the projection of the second connecting means latches behind the latching projections of the circular bore of the first connecting means.
