Abstract: A one-piece strain relief adapter is mounted on the rear end of an elongate electrical connector and carries pressure members for pressing against insulated conductors which have been inserted into insulation-opening contact portions of respective electrical contacts. The strain relief adapter carries a plurality of hook-shaped elements for positively aligning the pressure members with the conductors and for preventing ride-up of the adapter when these elements engage a forward facing surface of the electrical connector. The adapter also includes a yieldable resilient latch mechanism, preferably centered with respect to its ends, to engage a shoulder at the rear end of the electrical connector for holding the adapter to the electrical connector and for preventing bulging at the center of the adapter. The adapter also has a recess for slidingly receiving an internal rib of a hood and a forwardly facing surface which engages the internal rib to prevent removal of the hood in the rearward direction.
