A buckle device includes a base coupled to a strap, an operating arm is rotatably secured to the base with a stationary axle, a shaft is attached to the operating arm. A latch is slidably attached to the operating arm to selectively lock the operating arm to the base. Another strap has an intermediate portion engaged around the stationary axle to form two strap segments, the shaft may force the strap segment to tighten the straps when the operating arm is moved toward the base and locked to the base at the locking position with the latch, the stationary axle and the shaft are spaced from each other for a distance to allow one of the strap segments to be further pulled by a user and to further tighten the straps.
