The invention relates to an expanding mandrel having a sleeve-like main part (2) in which an adjusting rod (3) for adjusting at least one sliding pin (4) supported by the wall of the main part (2) is longitudinally movably arranged. A guide pocket (8), which is associated with the sliding pin (4), is formed in the surface of the adjusting rod (3), extends in the longitudinal direction and is off center with respect to the longitudinal axis of the adjusting rod (3).
