Several finger-like grippers (4) are held and guided in openings or holes (21) in the head part (6) of a housing (20) so they can pivot about axes which are in a common plane transverse to the longitudinal axis (L) of the housing (20). Permanent magnets (11, 12) fixed to the inner ends of the grippers (4) cooperate with an electromagnet (13) provided in the housing (20) above the magnets (11, 12), the magnetic field axis of the electromagnet coinciding with the longitudinal axis (L) of the housing (20). The electromagnet moves the inner ends of the grippers (11, 12) back and forth between two stops (16, 17) depending on the polarity of the electromagnet (13).
