1. A side-bar assembly for attachment to a chassis of a pick-up truck, off-road vehicle or the like capable of being mounted on such vehicles of a plurality of different sizes and configurations, the side bar assembly comprising a pair of substantially L-shaped tubular members forming half-bar tube sections to collectively form a generally U-shaped side bar to extend laterally from a side of the vehicle wherein the U-shaped side bar includes a pair of transverse parallel side-legs to project substantially perpendicular to the vehicle longitudinal axis and a connecting cross-leg to extend parallel to said axis, the L-shaped tubular members being of predetermined outer radius and each having a first straight tube leg to form one of the side-legs of the U-shaped side bar and having a second straight tube leg connected to the first tube leg by a curved substantially 90°

  • bend to form the cross-leg of the side bar, a substantially semi-cylindrical connector sleeve defining a concave tube-gripping recess having a radius over a portion thereof corresponding substantially to said outer radius of said second tube legs to receive the latter therein in alignment with each other with the connector sleeve partially encircling and gripping adjacent portions of the second tube legs over more than half a circumferential extent of each, and mounting means for bolt securement to the vehicle chassis to receive and support end portions of the side-legs therein, said connector sleeve being an axially elongated cylindrically curved body having a partially encircling inwardly concave abutment surface to engage and conform to confronting exterior surfaces in the tube legs along the axial length of the sleeve for at least about a quarter of the circumference of the tube legs and having an uppermost part thereof shaped to define a step-on tread-forming portion to abut the tube legs along a longitudinal line at a tube leg location diametrically opposite portions of the tube leg engaged by part of said concave abutment surface.
