Abstract
A method of applying a metal sleeve to a concrete reinforcing bar by introducing between opposed surfaces of the sleeve and the bar, particles having a hardness greater than that of the bar and the sleeve and then compressing the sleeve on to the bar with a sufficient force to cause the particles to bite into and grip both the bar and the sleeve. The metal sleeve may be provided as having on its internal surface particles of the foregoing properties. The swaged connection is achieved by carrying out the foregoing method. The invention also contemplates a concrete reinforcing bar with the swaged connection.
