Arrangement of building elements with connecting means

An arrangement of building elements having a flat surface comprising:

• a) a plurality of building elements capable of separable connection to one another using a tongue, a first groove, and connection means;
• b) wherein the tongue comprises a different material than the building elements;
• c) wherein the first groove is defined by two arms designed to be resilient and that the tongue can be inserted into the first groove
• i) the first groove is formed directly in a second one of the building elements;
• ii) the width of the first groove increases from an inside to an outside;
• iii) a thickness of the tongue decreases towards a free end
• iv) the tongue having a front surface enclosing a first angle relative to a large flat surface of the building elements and having a shorter rear surface adjoining a latter surface and enclosing a second angle, which exceeds the first angle relative to the large flat surface of the building elements, thereby forming a kink;
• v) the first groove provides a contact surface close to a base of the first groove, which, in a locked position, is at least partially in contact with the front surface, and the shorter rear surface, remote from the base of the first groove, which in the locked position, is in contact with the shorter rear surface of the tongue;
• and
• vi) at least one of the arms of the first groove being bendable outwards in a resilient manner relative to the second arm of the first groove in each case, so the tongue is held in a resting position by the arms of the first groove subject to a clamping effect;
• d) wherein the tongue is inseparably connected to the connecting means;
• and
• e) wherein the tongue via the connecting means is inseparably connected to a first one of the building elements by a form-fit connection and the tongue is connected in a separable manner to the second one of the building elements, said connecting means contacts a second groove of the first one of the building elements and penetrates and hardens in openings and pores in the second groove in the first one of the building elements wherein the angle of the tongue front surface enclosed relative to the large flat surface of the building elements is greater than an angle enclosed by a region on the first groove close to the base of the groove relative to the large flat surface of the building elements.
