A buckle for belts comprises a first shell unit having a releasing piece, a second shell unit connected under the first shell unit, a locking element pivotally connected to a seat of the second shell element, and a moving element movably installed behind the locking element. When a strap-connecting element is inserted into the buckle from a front end thereof, the locking element is pushed and is pivotally rotated by the strap-connecting element to make the locking element lock the strap-connecting element. Simultaneously, the moving element is moved to support the locking element so that the state of the locking element firmly securing the strap-connecting element is maintained. When the releasing piece of the first shell unit is actuated, the moving element is cooperated by the releasing element and no longer supports the locking element to release the state of the engagement between the locking element and the strap-connecting element.
