The invention relates to a method for connecting at least two planar components which are lying one on top of the other, using a connection element that comes to a point and ends as a conical surface. The rear part of the connection element is provided with grooves and, by applying pressure and rotating, it is driven through the components which are to be connected, with the rotation of said connection element being brought to a stop once a passage has been formed out of the material of at least the lower component. The connection element is secured in place in relation to this passage under the pressure of the material entering into the grooves. |
