A tube fastener, with a binding wire, both ends of which are made of a spring steel wire and which is wound in coil form, with the ends in crossed relation to one another, such that one end of the binding wire is bent transversely and attached to a supporting plate, and the other end of the binding wire is fixed to a pressing plate and where a screw spindle is fitted to the pressing plate by passing through it, and at the same time, the extreme end of the screwed spindle penetrates the supporting plate and is restrained by one end of the wire, where the wire is being retained by the supporting plate in such a way that the extreme end of the spindle may make free revolutions, with a pressing piece projected on the pressing plate, the extreme end of which is set in a manner such as to press the surface of a tube, and by the revolutionary operation of the screw spindle, the supporting plate and the pressing plate are brought close together and separated alternately, thereby tightening and loosening the steel wire and because of the fact that the pressing plate is capable of tightening the binding effect of the steel wire to a stronger degree due to its reaction force. |
