Abstract
The tool comprises pliers (5) mounted in an extension of a shaft (2) mounted to rotate around its axis in tubular sleeve (4). Metal wire (14) can be engaged in an axial bore (12) of shaft (2) and between the jaws of pliers (5). The tool makes it possible to fasten two elements (17,18) to one another by means of the wire (14) by a pull exerted on the sleeve (15) of the tool which, in a first stage, wraps the ends of the fastener engaged between the jaws of the pliers (5), around one another, and, in a second stage, separates the fastener from the wire (14).
