An electrical connector with a coupling state indicating mechanism is provided, which includes: a first connector having a semicylindrical projection; a second connector having a slider receiving portion and to be coupled with the first connector, the slider receiving portion being provided with a guide groove to guide the projection and with an abutting plane; and a slider to be slidably received in the slider receiving portion for indicating a coupling state of the first and second connectors, the slider having an engaging projection to prevent coming-off thereof, an oblique cam groove to receive the projection therein so as to slide the slider toward the abutting plane, a releasing groove continuing from the cam groove to release the projection from the cam groove when the first and second connectors have completely coupled so as to return the slider to an initial position, and a spring portion to abut on the abutting plane and to be compressively transformed to bring about a force to return the slider, wherein a curved surface of the projection slides on a wall of the cam groove so as to attain smooth sliding and a plane surface of the projection is parallel to the releasing groove so as to surely shift the projection from the cam groove to the releasing groove. Thus, the slider is moved and abuts on the abutting plane in a process of coupling the first and second connectors and then returns to the initial position upon complete coupling thereof.
