Abstract: In order to provide a secure connection which can be produced in a simple manner by the pressure die casting method between edge strips (3) inserted in the step plate (2) of a step element and the step plate (2), the edge strips (3) have on their underside at least along their two longitudinal edges a respective tongue (6, 7). The cross sections of the latter two have the shape of a parallelogram with mutual identical angles or of a trapezoid and engage in corresponding grooves (8, 9) in the step plate (2) in the manner of a tongue-and-groove connection. Furthermore, these edge strips (3) are provided on their underside moreover with at least two cast-on locking pins (10) which extend downwards and through the adjacent step plate (2), and on whose free ends projecting downwards out of the step plate (2) a respective clamping ring (11) is clamped resiliently supported on the underside of thhe step plate 2.
