Abstract: A clip is disclosed for insertion in a hole in the side of a paving form. A paper sleeve, diamond-shaped or rectangular in cross section, covers one leg of a tie bar, and the sleeve is supported in the clip. After a slab is poured and the form is removed, the clip and hole identify the position of the tie bar, which is pulled outwardly in preparation for the next pour. The rectangular protective sleeve can be used without the clip, in that it positions the leg of the tie bar closely adjacent the paving form, without the interposition of extra concrete around the edges of the sleeve.
