A connector is provided which includes engaging portions for engaging hooks formed on the upper arm portion of each terminal, an actuator having two contact pressure portions formed on each of two end surfaces positioned on opposite sides from each other in the left and right direction, and a housing having two holding portions opposing each other on the left and right sides and interposing the actuator. The holding portions press against the contact pressure portions of the actuator in a second position and do not press against the contact pressure portions of the actuator in a first position, where the position of the actuator when the engaging portions are engaging the hooks is the first position and the position of the actuator when the engaging portions are not engaging the hooks is the second position.
