The invention relates to a skid plate, which is one of the components cooperating with each other, allowing the coupling of a semi-trailer with a truck tractor and a fifth wheel with which the semi-trailer tractor is equipped.The skid plate is a bent, monolithic, contoured area of the surface (1). It has circumferential ribs (2) and a central, longitudinal embossment (3), which increase the bending strength, of a preferably hydroformed skid plate, and improve its stiffness. The longitudinal embossment (3) is flattened in the area the surface (1) is joined to the king pin (5). The longitudinal embossment (3) runs exactly through the centre of the surface (1) and constitutes the axis of symmetry for the ribs (2). The centre (4) of the elliptical shape of the ribs (2) is located in the space of the longitudinal embossment (3). At the centre point (4) of the hydroformed skid plate there is located a king pin 5, which is mounted in the fifth wheel of a semi-trailer tractor as a result of coupling the semi-trailer with the semi-trailer tractor.
