Claim:
1. An assembly for the placement of concrete, comprising: a clip member having a tubular base, said tubular base having a unitarily formed surface support member positioned on a top end thereof, said surface support member being planar, and having four upstanding parallel protruding walls defining a central channel and a first and second outer channels on said surface support member, said four upstanding parallel walls defining the central channel having inwardly facing flanges at an upper edge; a large-profile screed guide, suitable for use in the placement of concrete slabs of a depth superior or equal to six inches; and a small-profile screed guide, suitable for use in the placement of concrete slabs of a depth inferior to six inches, each of the large-profile and small-profile screed guide having a linear shape and comprising: a base member, and two side walls extending upwardly from the base member and joined at an apex, forming a generally triangular-shaped longitudinal cavity, the large-profile screed guide comprising unitary side walls which extend outwardly from a central member and curve downwardly, each side wall terminating in an inwardly extending flange, thereby defining two parallel longitudinal open channels, wherein the assembly is dimensioned so that the central channel of the clip member is able to snap-fittingly receive the central member of the large-profile screed guide, whereas each of the first and second outer channels of said clip member is able to snap-fittingly receive the inwardly extending flange of one of the side walls of said large-profile screed guide, and the central channel of the clip member is able to snap-fittingly receive the base member of the small-profile screed guide, the clip member receiving either the large-profile or the small-profile screed guide.
