The lateral groove flanks (4′b, 4″b) in the expanded groove portion (4), while reducing the mutual spacing thereof from the groove base (4c), run at an angle (γ) of 5° to 25° in relation to the radial direction and in the direction of the circumferential extent of said lateral groove flanks (4′b, 4″b) run in a wave form
