A plastic pallet described herein may have a plastic upper deck with an upper side on which goods can be stacked. Furthermore, a plurality of plastic skids are present, spaced apart from the upper deck and arranged substantially parallel to the upper deck. Plastic spacer blocks are located between the upper deck and the skids. The upper deck and the skids are manufactured as separate parts which in an assembled state are tightened together by tightening pins. The tightening pins each extend through a bore in each of the spacer blocks and corresponding holes in the upper deck and the skids.
