Abstract
The secure release apparatus is used with an anti-theft device having a member which is movable in response to an applied magnetic field. The secure release apparatus comprises a cover plate with an access opening and a permanent magnet structure which produces a concentrated magnetic field sufficiently strong to move the member. A tamper prevention structure is movable into a first position for preventing the member from moving into the concentrated field.
