Abstract

The device comprises two parts made of fairly rigid material. One part (1) is a collar with a central hole (2), the surrounding material having a conical shape (3, 4). The included angle of the cone is about 150 deg. The second part is passed through the sheets, and comprises a round head (8) and a shaft. The shaft is formed by two conical pieces (6, 7). The widest part of the shaft is of slightly larger diameter than the central hole in the collar. The cross-section of the hole is shaped to correspond with the lower conical part of the shaft. The shaft can be solid, hollow or have a hole through it, or can have a point so that it can be pushed through the material.
