Abstract

This device is constituted by a set of four pre-drilled identical segments (1), these segments being capable of being assembled in pairs in order to form two rigid articulated assemblies to be mounted in liaison on each side on the uprights (9) of the ladders in order to couple them rigidly in position with respect to each other. <IMAGE>
