Certain embodiments of the present invention provide a buckle for fastening opposing ends of an object encircling strap (120). The buckle includes a deformable retainer (130) and a bridge (140). The deformable retainer defines an entrance passageway (150) for a free end of the strap and includes a retainer tab (131), an opening (132) adjacent the retainer tab, and a pair of strapping supports (133) spaced apart from the opening. The bridge defines an exit passageway (160) for the free end of the strap. The free end of the strap is positionable around an object and consecutively through the entrance passageway and the exit passageway. The free end of the strap is bendable over the bridge and between the strapping supports and the opening such that the free end of the strap curls when the retainer is deformed.
