A reinforced connector assembly for a tubular grab railing has an upper tubing support that is aligned with the grab railing during use and a lower base portion bolted directly to the tubing support fastened to a wall or floor. The tubing support has an opening that divides it into upper and lower halves with a reinforcing plate hidden between them to form a three layer sandwich structure with at least one boss confined during use within the tubing. The connector assembly is a composite formed from an outer plastic resinous connector element and the hidden reinforcing plate which can be formed from steel. The reinforcing plate which provides reinforcement for the plastic components can include exposed ears on each side that frictionally engage and distend the tubing to prevent it from rotating during use. An adjustable connector assembly has two pivotally related portions to permit angular adjustment on site. A corner elbow, an end connector and an end extension are provided.
