Abstract

A mechanical connection for concrete reinforcing rods lacking a threaded end or the like comprises - a sleeve (11) with a cylindrical hollow body into which is introduced axially the end of the reinforcing rod (7) which has no connecting element; - a coaxial threaded portion (8) on the end of the sleeve (11); - the outer material of the sleeve (11) having undergone deformation by necking-in in the area of the end of the reinforcing rod so that - the material of the ribs (10) on the reinforcing rod also deforms in order connect the reinforcing rod and the sleeve. This deformation may be produced by a piston (21) and die (23) of a jack screwed on to thread (8). After removal of the jack, the further reinforcing rod is attached via thread (8). <IMAGE>
