Abstract: A self-locking clip assembly for decorating garment strap comprises a first piece and a second piece. The first piece comprises a first flat surface that serves as a platform to affix decorative ornaments, a bridge connected to the first flat surface and a channel. The second piece comprises a second flat surface and a third flat surface, wherein the third flat surface has a curved indentation that matches the shape of the bridge, such that the curved indentation is flush with the contour of the bridge to lock the assembly. The garment strap is allowed to slip through bridge of the first piece and rest in the channel of the first piece. As a person wears the garment strap, the wearer's body presses against the third flat surface, consequently pressing the second flat surface against the strap and the first flat surface to automatically lock the clip assembly in place.
