A dowel pin (1) according to a first aspect with a cylindrical body (4). The cylindrical body (4) is divided into first and second parts (2,3). The first part (2) is movably connected to the second part (3) allowing only relative transverse movement between the first and second parts (2,3). According to a second aspect, the dowel pin (1) comprises a cylindrical circumferential surface (5) and first and second longitudinal ends. The circumferential surface (5) comprises a first plurality of primary radially lifted contact areas (33) at a first distance D1 from the first longitudinal end and a second distance D2 from the second longitudinal end, with D1 being less than D2, and a second plurality of secondary lifted contact areas (35,36) at a third distance D3 from the first longitudinal end and a fourth distance D4 from the second longitudinal end, D3 being larger than D4.
