Object transfer device comprising a frame (3,20,63,58), at least one gripper (6,22,22a,62,57a,57b) having a gripper body (7,25,45) and means of guiding the gripper body with respect to the frame; the gripper being equipped with one or more jaws (8,28a,28b,46) mobile with respect to the gripper body (7,25,45). The gripper comprises a magnetic element (12,32,44,52,56) capable, when it is subjected to a magnetic field greater than an efficiency threshold, of exerting a force on at least one mobile jaw. The frame comprises a control device (24,49,50) of the gripper capable of creating a magnetic field greater than the efficiency threshold in at least one zone (14,15) of the frame dedicated to the operation of the gripper. Said gripper body guide means is designed so that the magnetic element of the gripper is driven in translation along a movement path (13,33) passing through the operation zone (14,15) of the gripper defined by the control device (24,49,50).
