<p>The present invention relates to a buckle device locking a releasable elastic string. The elastic string includes a plurality of annular protrusions on the circumferential surface thereof in the lengthwise direction. The buckle device includes a buckle housing and a buckle. The buckle housing includes a pair of locking pins spaced apart from each other and a passage formed between the locking pins, wherein the elastic string is hung on each of the locking pins and passes through the passage. The buckle is movably coupled to the buckle housing between the elastic strings in opposite first and second directions perpendicular to the plane passing through the central axis of the locking pins. The buckle includes a latch protrusion which is hung with the annular protrusion on the surface facing the locking pin thereof. The latch protrusion allows the elastic string to press the locking pin by the movement of the buckle in the first direction to fix the elastic string to the locking pin. The elastic string may be quickly and reliably locked using the locking pin by means of the contracting force of the elastic string.</p> |
