A buckle for harness includes a ring member, a bar member and an elastic sheet. The ring member includes two opposite side portions and a cross portion connected with the side portions. A shaft pivotally connected with the side portions is disposed on the bar member for the bar member rotating relative to the ring member. A protruding portion sticks out from the shaft. The elastic sheet includes a fastened end secured to the ring member and a free end firmly abutting against the protruding portion with a rebounding force generated by the elastic sheet. An angle θ defined between the protruding portion and the free end changes as the bar member rotates. The bar member keeps standing if the angle θ is greater than 90 degrees.
