A hookless coupling device for releasable connection to a sports harness includes an elongate body having a connector end for connection with the sports harness, an engagement end, and an elongate aperture extending between the connector end and the engagement end for engaging an engager. The aperture is wider at the connector end than at the engagement end. The sports harness includes a band for surrounding the waist or hips of a person, and the elongate body. A sports device, releasably engagable to the harness, has a spherical engager tethered with a line. The aperture passes the spherical engager though the engagement end and the engager is moved to the connector end. A sports kite includes a canopy, a traction line having a first end tethered to the canopy, and a second end to which the spherical engager is connected.
