The present invention provides a magnetically attractable fastening device. The device comprises magnetically attractable ends joined together by a flexible bridge. The magnetically attractable ends each comprise at least one magnetically attractable element. At least one of the elements is a permanent magnet. The magnetically attractable elements are positioned in the ends of the device to provide a differential magnetic field at each end. The magnetically responsive elements are encapsulated in a non-magnetic material. The bridge that joins the ends of the device also comprise a non-magnetic material.
