A buckle includes a base, a one-piece handle and an elastic element. The base is made of a metal sheet by pressing and includes two walls, a floor between the walls and a jaw between the walls. The one-piece handle is made of a metal sheet by pressing and includes a touch portion at an end and a jaw near the touch portion. The one-piece handle is installed on the base to define a gap between the jaw of the base and the jaw of the one-piece handle. The one-piece handle can be pivoted on the base between a first position where the gap is small and a second position where the gap is large. The elastic element tends to keep the one-piece handle in the first position.
