A sliding track connector for mounting objects to a track member using a twist or zip ties. The connector includes a body with a bottom surface, outer sidewalls, a center void, and a plurality of transversely aligned holes. In one embodiment, a post extends downward from the body's bottom surface and slides freely inside the slot formed on the track member. Attached to the post is a wide cap that, when twisted, presses against the inside surfaces of the flanges formed on opposite sides of the slot. In one embodiment, the post and cap are integrally formed on the body so that when the body is rotated, the post rotates inside the channel, and the cap becomes wedged against the flanges on opposite sides of the slot. One or two twist ties are inserted through the holes on the body to hold an object on the track member.
