ABSTRACT:
A stretcher for stretching wires and similar elements for use in fences and the like which comprises a yoke to be attached to a post or similar element, the outer portions of the yoke being provided with two opposite apertures, and a rotatable stretching element disposed between the outerportions of the yoke and provided with a through cross-aperture in which a wire to be stretched can be received. The rotatable stretching element is provided with a threaded outer end having a cross-section smaller than the stretching element, thus forming a collar, and substantially equal to the cross-section of the aperture of associated outer portion of the yoke and an associated nut. By tightening the nut, the associated outer end portion of the yoke is gripped between the collar of the stretching element and the nut.
