A guide rail has running surfaces separated by a longitudinal slit and a load bearing member carried by the same so that it may slide but not rotate and on it a closing element, preferably a door of a folding sliding door, is attached. In order to be able to secure the closing element carried by the load bearing member to the guide rail simply and quickly, the load bearing member has an elongated carriage part running in the guide rail and having a width corresponding to the longitudinal slit in the guide rail. In a hole, at a right angle to the guide rail, in the load bearing member a pin is mounted so that it may rotate but not move axially and adjacent to carriage part it has a T-head, whose width is less than the width of the longitudinal slit but whose length is greater than it. The pin is able to be locked to the load bearing member in a setting in which the head bears against the running surfaces.
