Abstract
Abstract A box-shaped main plug unit is connected at one end to a cable. A plug of the main plug unit is insertable into plug insertion openings of a connector socket. A lock claw of a lock member is affixed to the main plug unit, and is positioned to lock into latch openings of the plug insertion openings. A slider is slidably supported on the main plug unit. When the slider is slid on the main plug unit it forcibly disengages the lock claw from the latch opening. A pull-out handle is rotatably supported on the slider. The pull-out handle is rotatable between a protected inoperative position and a projecting operative position where it permits application of removal force on the main plug unit. A fixed projection is integrally formed on the slider to further aid in the application of a pull-out force to the main plug unit.
