The wedging key is of considerable length and projects inwardly to some extent beyond the collar 13 and the adjacent washer l6 and also extends outwardly to a considerable distance therefrom so that it can be conveniently driveiito position. In order that they may be of sufficient strength, the wires, collars and wedges of the tie are 'preferably formed of hard steel. The wedges may-be in theform of ordinary cut nails having parallelsides and tapered edges. However, as mostclearly shown in Fig. 5, the width of the'wedge is slightly less than the widthbfthe slot 12 in the collar, s0 that itwill be heldby the tie wires 10 out of frictional contact withthe col-' lar and rapable of exerting its maximum clampingaction upon the wires In the ,preferred form shown, the key 15, instead. of tagrooves or seats 19 which'fitthe wires and in crease the surface, contact :andthe: grip of the wedgeuponthe wires.- Also, the wedge is provided with shOuldersQO having inclined grooves or seats for. the wiresand which are arrangedto spread the ends of the wires and bent or ofisetthem over the outer edgeof the I wardly through the opening and between the collar opening. In thisway, the ends of the -,wi1'es arecrimpedior interlocked with the collar tohold thelatter more firmly in posi ,tion andprevent the spreading of the mold mus Preferably, also, the edges of the wedging key are provided with. recesses 21 between the shoulders 20 and the Wedge portion 18 which receivethe rounded bends of the wires and into which portions of the wires are slightly offset as thewedgeis driven to positionrto firmly interlock the latter with the, wedge. Obviously, with the arrangement shown, strain upon the tiedue to the pouring of theconcrete will tighten the grip between the wires, collar and wedge.

A modifiedform of wedging key 15 is shown inQFigsUGjandi'Z; This form is provided witha wedge portion 18 and inclined shoulders 20, but the recesses ,betweenthe wedge portion and shoulders are omitted. Preferably, as shown, the edges ofthe wiring seats "19'. in this form, are provided with nicks or notches 22 to form teeth for gripping the wires. g V I Asshownin Figs.3 and- 4, the washer 16 is provided with a circular opening 23 which is slightly less in diameter than the length ties and the ties will stoutly resist pressure on the mold-walls so that the concrete can be rapidly poured. When the concrete has set, thetie wires can be readily cut to permit removal of the form and the wires can be cut ofi flush with the face of the concrete or withdrawn.. t herefrom,as. desired. .Also, if the wires are left in the concrete, theirlpro- 'jectingends can be readily twisted off by applyingza. wrench to thetie collars which are preferablyv square. v
