Abstract: The device is for moving a person of reduced mobility, in particular to move a person between two horizontal supporting structures disposed close to one another. The device has at least one movement element formed by a horizontally planar base and a supporting element. It is possible to move the base in relation to the supporting element by combining a guiding device with a pulling and gripping device so that the base is moved rectilinearly between end positions defined by the front and rear edges of the supporting element (3) when the element is being held stationary under a vertical force. The supporting element is formed by a plate that has a lower surface that has at least one rectilinear longitudinal rail that is engageable with at least one corresponding groove provided on the upper wall of the base.
