Disclosed herein is a connection device for tractor implements. The connection device includes a main frame (200), a slider body (400) and an implement connection unit (300). A distance adjustment cylinder (250) is installed between the slider bodies. A slider (430) is slidably provided on each slider body. A locking rod (410) is provided in an upper portion of the slider body so that a hook (316) of the implement connection unit is hooked over the locking rod so as to be slidable. A connection part (420) is provided on a lower portion of the slider body such that, when the slider body slides, the connection part is coupled to a fastening part (317) of the implement connection unit. When the distance adjustment cylinder is operated, the distance between the slider bodies is adjusted and the fastening part and the connection part are coupled to or separated from each other.
