Claim:
A combination comprising: a pair of panels for use in constructing a poured concrete structure, each of the panels having a flange extending from a face of the panel, each flange having at least one aperture formed therethrough; a pin having an enlarged head and an elongated shank extending between the head and an end of the pin, the shank having a through slot spaced from the head; a tapered region on the shank of the pin, the tapered region extending from the end of the pin to include at least a portion of the through slot; wherein the tapered region further comprises a first portion and a second portion each extending axially on the shank of the pin, a slope of the first portion being different than a slope of the second portion of the tapered region; and a wedge having a first end which is larger than a second end thereof, the second end being sized to pass through the through slot and the first end being sized not to pass through the through slot; wherein the end of the pin is inserted into and through the apertures in the flanges of the panels and the head preventing the pin from passing entirely through the apertures, the flanges of the panels being juxtaposed to one another and the second end of the wedge inserted into and through the through slot to releasably couple the panels together and the tapered region facilitating removal of the pin from the apertures after the wedge is withdrawn from the slot; wherein a juncture between the first and second portions intersects the through slot.
