Abstract
A railing system suitable for decks, stairs, porches and other structures uses a collar connector applied over the open end of a tabular rail for securing the rail to a support surface. The connector has an exterior collar into which the open end of a railing is inserted. The railing is also engaged on the interior of the railing by an inserted plug. The railing is trapped between the inserted plug and the collar whereby a tight connection is achieved. The gap between the inserted plug and the exterior collar narrows from the open end of the collar towards the base.
