The positioning aid includes an elongate fastening portion to which at least one nut is fastened and which is dimensioned such that it can be passed through one of the elongated holes together with the at least one nut and moved within the hollow rail. The positioning aid also includes a holding portion for holding the fastening portion, the holding portion being fastened to one end of the fastening portion and being configured to be wider than the elongated hole.
