Here is disclosed a connector for connecting a tool with a tool bit including a polygonal portion formed thereon and an annular groove defined therein. The connector includes a socket, a detent, a sleeve and a positioning device. The socket includes a polygonal hole axially extending in an end thereof, a space in communication with the polygonal hole and an aperture extending through the socket in a radial direction. The detent is received in the aperture. The sleeve includes a recess defined in an internal face. The sleeve is rotationally mounted on the socket between an unlocking position and a locking position. In the unlocking position, the recess is aligned with the aperture so as to receive a portion of the detent in order to allow complete removal of the detent from the space, thus allowing insertion of the polygonal portion into the polygonal hole. In the locking position, the recess is not aligned with the aperture so as not to allow complete removal of the detent from the space so that the detent is partially received in the annular groove defined in the tool bit. The positioning device retains the sleeve in the unlocking position or the locking position.
