A lateral guidance device including a hollow guide located along conveyor track of a goods-handling system on which products are guided laterally, composed of profiles that fit together with each other, each with an inner face and outer face, one of which is used for guidance purposes. An expandable chamber, housed in the hollow guide, is supplied with expansion fluid from a supply means. The outer faces are returned in to a position of minimum distance (dmin) between these faces by return means, when the fluid feed to the expandable chamber ceases. Thus, the distance between the outer faces is proportional to the supplying of the chamber with expansion fluid, between a minimum distance (dmin) and maximum (dmax).
