A fastening arrangement (14) comprises a shank (16) with a head (18) retained in a first component (10). The other end (25) of the shank is tapered or of other non-constant cross section and terminates in a domed portion (26). A second part of the fastening arrangement includes a collar (34) of shape memory metal material, which may be swaged to engage and retain the domed portion (26) by a magnetized pressure ring (36), which is applied by applying a strong magnetic field. To release the fastening, the pressure ring is released by the application of a magnetic field and the collar (34) is then heated so that it reverts to an open position.
