A suitcase comprising: - an enclosure defining an inner volume, the enclosure comprises a first shell, a second shell and a hinge device connecting the first shell and the second shell, - a zipper fastener extending along a junction plane and comprising a first strip presenting a first edge, a second strip presenting a second edge, a slider and a pull tab connected to the slider, the slider is movable between: • a fastening position in which the first edge is maintained adjacent to the second edge, and • a releasing position in which the zipper fastener releases the first edge in relation to the second edge, - a lock device fixed to the enclosure and adapted for cooperating with the pull tab in a locked position in order to maintain the slider in the fastening position and, the second shell is movable in relation to the first shell between an opened position and a closed position through the hinge device when the slider is in the releasing position, the suitcase being characterized in that: - in the fastening position, the lock device and the pull tab are arranged in the junction plane, - the suitcase presents a flat surface in which the lock device and the hinge device are arranged, - the hinge device comprises an intermediate element rotatably hinged in relation to the first shell around a first articulation axis and in relation to the second shell around a second articulation axis, - the first articulation axis is parallel to the second articulation axis, and - the lock device is carried by the intermediate element, - in the closed position, perpendicular to the junction plane: • the lock device presents a part situated outside the enclosure and presenting a space width, • the first rotational axis is separated from the second articulation axis by a gap distance, and the gap distance is equal to or greater than the space width. -
