An electrical connector with contact locking bodies separate from a housing which are secured from accidentally falling off the housing and prevent foreign matters from entering the connector through a gap between the contact locking bodies or through gaps between the contact locking bodies and the housing. The electrical connector includes a lower housing having a recess that opens in an upper surface, a contact that passes through the recess of the lower housing in the front-rear direction and is received therein, a lance block that is received in the recess of the lower housing from above the upper surface and prevents the contact from falling off, and an upper housing that is positioned on the upper surface side of the lower housing to cover the lance block.
