Abstract: An adjustable buckle for a ski shoe or the like and which is infinitely variable without the necessity of threaded bolts or similar adjusting mechanisms. The buckle includes a base plate for being secured to the shoe and which base plate has an upper and lower surface, a locking holder is shiftably mounted on the base plate for bodily shifting in a longitudinal direction along the length of the plate, and the holder is also mounted on the plate whereby it can oscillate relative to the plate and about an axis which is generally transverse to the longitudinal shifting axis of the holder. The holder carries locking means for releasably locking the holder relative to the plate and which locking means engages the opposite surfaces of the base plate. Simply by oscillating the locking holder in one direction or the other about its transverse axis, it can be locked to or released from the base plate.
