A device for conveying a cap-type capping elements, which are pushed aeraulically to circulate the capping elements in a forward direction. In example embodiments, the device includes firstly an elongate plenum in which a gaseous fluid circulates, and secondly a channel in which the capping elements circulate in a forward direction and that has a front face, a rear face, and two edge faces. In example embodiments, the device comprises an aeraulic circuit to convey the gaseous fluid from the plenum to the channel to push the capping elements, the rear face of said channel being arranged against the plenum and the front face thereof being at least partially closed by a back-plate of the device. In example embodiments, the back-plate may be removable.
