The disclosed safety device includes a barrier member disposed on a departure landing in front of a guide port for receiving a moving handrail after having been turned in its traveling direction. The barrier member is provided on the upper surface with a C-shaped groove having an opening narrower than the width of the handrail and formed of two sections of easily destructable material divided in a plane extending lengthwise of the groove. The handrail is loosely inserted into the groove. The barrier member may be provided on each of its lateral side surfaces with a notch in the form of a semi-arch.
