摘要： There is described a securing device (10) for releasably securing a first object to a second objection. The device comprises a casing (12) and a coupling magnet (22) housed in the casing. The casing is configured for being inserted in a passageway formed by aligned openings (54, 60) of the first and second objects when assembled together, for blocking separation of the first object and the second object from one another. The coupling magnet (22) is moveable from an initial position to a working position to form a magnetic coupling for holding the casing in the passageway. The first and second objects can respectively be a tooth (50) of a mining or excavation bucket and an adaptor (52) of the bucket for the tooth (50). A fixed magnet (28) can be provided in the casing (12), the fixed magnet (28) being oppositely poled with respect to the coupling magnet (22) for damping the movement of the coupling magnet to its working position. There is also provided a removal tool (178) for removal of the securing device from its securing position. The removal tool includes a coupling magnet (180) for being moved from a retracted position to a coupling position for magnetically coupling with the securing device (10) for releasing the coupling magnet (22) of the securing device from its working position and withdrawal of the securing device.
