Polarizing keys are provided to allow only selected pairs of connectors to be mated, which allow one connector to be displaced slightly after mating, while also providing a large area of interference between nonmating keys to prevent their connectors from mating. Each key has an elongated keying portion with an interfitting side 94 (Fig. 9) which lies opposite the interfitting side of a similar corresponding key when the connectors are mated. Each interfitting side has forward and rearward parts 120, 122, with the rearward part 122 being indented with respect to the forward part.
