An electrical connector that can prevent an unexpected length of time from being spent in separating the mated connectors is provided. The supporting portion is a plate-like member forming a slot in which a jig can be inserted in cooperation with the operation portion when the plug housing and receptacle housing are mated, and serves as the fulcrum point of leverage while the jig inserted in the slot and working as a lever abuts against the operation portion and deforms the elastic portion so as to disengage the latching portion and engaging portion.
