A composite article including a tubular body having a front end, a rear end, a peripheral wall extending between the front and rear ends, a wall support located rearwardly of the front end of the peripheral wall and at least one paragraph formed in the wall engaging support. An end cap is positioned on the front end of the tubular body to obstruct the wall engaging support except for at least a portion of at least one of the passages and to define a channel between the end cover and the peripheral wall. A plastic coating fills at least one passage in the channel and overlaps the cover to fasten the cover to the tubular body.
