The device has a deformable shutter displaced relative to a vertical bay in a direction to cover the bay or in an inverse direction to uncover the bay. A reintroduction element reintroduces lateral strips of the shutter in sliders, and has rollers (17), which are arranged relative to the sliders. The rollers are respectively placed on both sides of the shutter such that when the shutter is displaced in the inverse direction the rollers roll on the lateral strips, which are to be extracted from the sliders, by pushing the lateral strips in the sliders. |
