A joint connector is provided which can suppress the abrasion of contact parts due to relative displacements between wire-side terminals and a shorting member. The joint connector includes a plurality of wire-side terminals (20), a shorting member (30) including a base portion (32) and a plurality of terminal fitting portions (34), and an insulating housing (HG) defining a plurality of terminal accommodating chambers (41) and configured to hold the shorting member (30). The insulating housing (HG) includes a terminal holding housing portion (40) defining the terminal accommodating chambers (41) and configured to respectively lock the wire-side terminals (20) and a shorting member holding housing portion (50) configured to hold the shorting member (30). The both housing portions (40, 50) are so connected while restraining each other as to allow relative displacements between the both within a limited range.
