Abstract
A hidden interconnection arrangement of fence or railing includes two or more engaging rails, a plurality of fasteners configured to pass through position holes of the engaging rails and fasten to fastening holes of a plurality of upright posts, and a pair of upper engaging arm and lower engaging arm integrally protruded from an inner surface of an engaging wall of a lateral beam, defining an engaging recess therebetween. A downward force applied to a top wall of the lateral beam is able to press a bottom guider edge of the lower engaging arm downwards against a top edge of the engaging rail that generates a reaction force to enlarge the bottom opening of the lateral beam to allow the engaging rail to be engaged in the engaging recess and locked between the upper engaging arm and the lower engaging arm of the lateral beam.
