A device for opening and closing a door for accessing hermetically sealed compartments, comprising an actuation lever (5), pivoted externally to the leaf (2) of the door about an axis (A) that is arranged along the edge and is parallel thereto, and is able to rotate from a closure configuration, in which it is arranged substantially parallel to the leaf (2), to an opening configuration, in which it is spaced from the leaf (2), the actuation lever (5) having a first actuation end (6) that forms a first longer lever arm for manually opening and closing the leaf (2), and a second end (7) that is provided with a tab (8) that forms a second shorter lever arm for engaging a locator element (9) that is provided laterally with respect to the edge of the leaf (2), the tab (8) being adapted to engage the element (9) when the leaf (2) is substantially ajar, so as to allow its hermetic closure by pressing on the actuation end (6). <IMAGE>
