A device, such as a gudgeon pin, for connecting a piston of a reciprocating internal combustion agent to a connecting-rod comprises at least in part a fibre-reinforced composite material. The device further comprises a metallic sliding bearing having a circular cylindrical external surface. The sliding bearing layer is arranged on the external surface of the fibre-reinforced composite material. A plurality of fibre layers, which run in differing directions, are arranged in the composite material, and the sliding bearing layer is divided in the transition region from a piston to a connecting-rod. The gudgeon pin has alternate layers, in which fibres are arranged orthogonally to fibres in an adjacent fibre layer. The fibres run parallel to the gudgeon pin axis in one layer and orthogonally thereto in the two adjacent layers. The composite material layer has on its exterior a metallic sliding bearing layer which is applied either by electro-plating or by vapour deposition, or a sliding bearing bush is slipped over the composite material layer.
