1. A backshell for connecting an overall-shielded harness comprising shielded cables to a connector, the backshell comprising a sleeve and an attachment ring,
the sleeve having a wall with a substantially tubular shape defining an internal passage for receiving shielded cables,
the wall of the sleeve comprising, from the front end to the back end thereof, an engagement area for engaging with a connector, through-holes distributed circumferentially for receiving the terminations of the cable shielding from the internal passage, a first external area for receiving the terminations of the shielding, an external shoulder, and a second external area for receiving the overall-shielding of the harness,
the attachment ring having a wall with a substantially tubular shape defining an annular passage for receiving the sleeve, the wall of the attachment ring comprising, from the front end to the back end thereof, an attachment area for connecting to a connector, a first internal area, and an internal shoulder,
the backshell being arranged in such a way that the attachment ring can slide over the sleeve in a direction going from the back end to the front end of the sleeve, to an abutment position in which the internal shoulder of the attachment ring abuts against the external shoulder of the sleeve,
wherein, in the abutment position, the internal area of the attachment ring covers the first external area of the sleeve, the attachment ring being thus arranged to cover the terminations of the shielding,
and the engagement area of the sleeve is a full toothed ring for engaging with the connector.
