Abstract
A connecting device for transport chains for the support and entrainment of plates for moving walkways or of steps for escalators of the type having two parallel chain runs to be joined together at a transverse spacing by connecting tubes serves to fasten the chain runs to the connecting tubes in a manner which facilitates subsequent detachment. Axle stubs of chain pins, which are constructed as support roller axles are pushed into the connecting tubes at both ends and are mechanically positively firmly held in an end position by slots in the connecting tube, a circular recess in the axle stub and a spring clip. The mechanically positive coupling is effected after the snapping of the spring clip through the slot into the circular recess of the axle stub, as in the end position of slot and circular recess are aligned with each other.
