An escalator safety apparatus covers the gap between the movable step and the fixed pedestal plates provided at both sides of a treadable stair belt with an elastic synthetic material lip. The lip is formed as a portion of a synthetic material insert section, which insert section can be mounted in corresponding recesses on both sides of step on the horizontal tread surface and on the arcuate riser. The lip adapts to variations in the spacing from the pedestal plate and has a very low coefficient of friction. The clearance for the passage of the step through a comb positioned at the upper and at the lower end of the travel path of the escalator need be enlarged only minimally and the insert with the lip is removable from the step disassembling the step from the stair belt. In alternate embodiments, the lip is formed on a support connected to the insert section.
