Removable separation device, in particular for an aircraft cabin

A removable separating device for an aircraft cabin, comprising:

• a fixed frame,
• a movable shutter, which is movable in translation with respect to the fixed frame between a stored position, in which the movable shutter is located predominantly inside a housing, and an extended position, in which the movable shutter is located predominantly outside the housing,
• said movable shutter having an upper edge, a lower edge, and two side edges extending between the upper edge and the lower edge, and
• two slide connections mounted between the fixed frame and the movable shutter,
• at least one of the two slide connections extending along a corresponding lateral edge of the movable shutter so as to authorize a translational movement of the movable shutter relative to the fixed frame,
• at least one of the two slide connections being formed by at least one roller carried by one of the movable shutter and the fixed frame cooperating with a corresponding rail fixed to the other of the movable shutter and the fixed frame,
• the movable shutter extends in a vertical plane when it is in the stored position and when it is in the extended position,
• wherein the roller has a cylindrical shape and is provided with a groove extending along its circumference, the rail being inserted inside the groove in the roller, so that the roller can move in translation along the rail.
