A device for clamping or immobilizing workpieces to be machined includes a casing adapted to be fixed to a worktable and in which is disposed a mobile part rotatable about a horizontal axis. The mobile part has a toothed sector cooperating with a lead screw. It also has an arm forming a lever whose end is adapted to bear on the workpiece to be machined. The arm is removably mounted in the mobile part and able to move in translation in a direction substantially perpendicular to the axis of rotation of the mobile part.
