Abstract
Work pieces to be galvanically coated or plated are held in place with a good electrical contact by a holding device having an electrically conducting hollow carrier (2), a magnet (3) removably mounted inside said hollow carrier (2) the ends of which are closable for protection of the magnet in a galvanic bath. A cover (4), with receptacles (28) or bore holes in which the work pieces or parts (12) are received, is clamped to the carrier (2) by a releasable clamping device (5). The magnet (3) is arranged alongside a contact surface (19) through which the magnet holds the parts (12), since the pole axis (P) of the magnet (3) extends perpendicularly to the contact surface (19) which may be formed by a machined surface of a carrier wall or by an electrically conducting ferromagnetic plate secured to the carrier.
