    Abstract: The railing system comprises at least one elongated rail having a plurality of spaced-apart openings. It also has a plurality of elongated pickets having opposite ends, each picket having at least one end provided with at least two spaced-apart retaining tabs initially extending lengthwise and configured to be inserted through a corresponding one of the openings of the rail. The tabs of the pickets are outwardly bendable to rigidly connect the pickets to the rail. This type of connection can be quickly achieved and lowers the manufacturing costs of railing systems.
