The frame has two sealing joints (11, 12) respectively positioned on a peripheral edge (3') of a window (3) and a peripheral edge (2') of a carrier structure (2). A detachable maintenance unit (20) maintains the edge of the window in one of the joints and the edge of the carrier structure in the other joint. The maintenance unit includes locking units (21, 22) cooperating with each other in a reversible manner for tightly fitting the former joint and the window and for tightly fitting the latter joint and the carrier structure. |
