ABSTRACT:
The device comprises a vertical pole (11) having a manipulating handle (14) at its upper end and a gripper (22) fastened to one end of a gripper support (20) mounted pivotally about a horizontal axis (21) at the end of the pole (11). Springs (25, 29) make it possible to return the gripper into a grasping position distant from the vertical axis ZZ' of the pole (11). A mechanism (24) for controlling the gripper in order to open and close it is carried by the gripper holder (20). This mechanism is connected to a remote-actuation mechanism by a flexible transmission element (37).
