The universal heavy bag hanger is used to secure a heavy bag to an overhead horizontal support member. The bag hanger includes a flat pad that has a length along a length direction to wrap around a support member. The pad includes a slip resistant material that engages the support member when mounted thereon. A strap is secured to the outside surface and extends beyond the longitudinal ends of the flat pad. A D-shaped ring is attached to one free end of the strap suitable for attachment to a heavy bag or the like. The other end of the strap is provided with a rectangular closed ring dimensioned to allow the D-shaped ring to pass through it to form a slip joint for tightening the strap about the pad, when increased load is applied to prevent or inhibit relative sliding movements between the hanger and the support member.
