A recreational structure, such as a trampoline frame, can be quickly and reliably assembled using a sleeve-joint coupling having a "T" configuration. A first arm member and an aperture that is formed in the sleeve-joint coupling are disposed in an opposite relationship. A second arm member and a third arm member are disposed in an opposite relationship with each other. The first arm member receives one end of a vertical frame member of the recreational structure, while the aperture receives one end of a vertical pole member of, for example, a safety enclosure. The second and third arm members each receive one end of a horizontal frame member of the recreational structure. The vertical pole member extends through the sleeve-joint coupling into an inner portion of the vertical frame member received by the first arm of the sleeve-joint coupling.
