Abstract: In a buckle for joining band ends together, one band end is provided with longitudinally arranged indentations in or adjacent each side edge, and a channel-shaped, adjustable coupling member of the buckle has teeth therein arranged to register with band end indentations at various relative positions and to penetrate the indentations when the band end is pressed against the coupling member. Presser members fixed to the sidewalls of the coupling member press the teeth into engagement with the indentations to maintain the coupling member in adjusted position. The other coupling member may be a cover which releasably engages with the adjustable coupling member.
