Releasable tie

Abstract

A releasable tie includes a locking element and a band. The band has first and second ends. The locking element includes a bottom plate, first walls, a second wall, and an operating rod. The bottom plate is formed with a window. A predefined gap is formed between the operating rod and the first walls. The operating rod has an arm extending therefrom and first meshing teeth thereon. An aperture is formed at such a position on the bottom plate that the projection of the arm lies at the position on the bottom plate. The band has a first top side and a bottom side with second meshing teeth thereon. The first and second meshing teeth are in mesh. The band is thinner than the bottom plate. The thickness of the band is larger than the distance between the top end of the first meshing teeth and the second wall.
