Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a connector for tunnel luminaire capable of easily pulling out a plug even when a cable having four cores is used as a dimming control cable. SOLUTION: The plug 11 is provided with a plug housing 12 wherein a body 12b having a large diameter and a tip 12a having a small diameter and inserted into a receptacle 17 are integrally formed, and the body is integrally formed with an insulating coating of the dimming control cable 6; and plug side contacts 16a to 16b provided in the plug housing and connected to a core wire of the cable 6. When the plug 11 is connected to the receptacle 17, a protruding positioning mark 19 used for determining the direction of the plug is formed on an outer periphery of the body 12b of the plug housing 12.
