Claim:
A multi-configuration muntin bar joiner clip for connecting two muntin bars to opposite sides of a third muntin bar having two side wall openings of generally the same width extending through the opposite sides of said third muntin bar in a first configuration and for connecting one muntin bar at right angles to a second muntin bar having a side wall opening located along a length of said second muntin bar at a region of contact with said first muntin bar in a second, altered configuration, said joiner clip comprising: a) a relatively flat, thin body for insertion into an interior of a muntin bar through a side wall opening and having i) opposite major faces, ii) substantially parallel side edges extending between ends of the body; and iii) a v-shaped notch that extends into one of the major faces of the body across a width of said body for separating the body into two body parts at a region of the v-shaped notch with one body part forming part of the second, altered configuration of said joiner clip having one end that extends across the body along the region of the v-shaped notch for insertion through the side wall opening of the second muntin bar; and one or more muntin bar abutments projecting from said flat, thin body for engaging an edge of the side wall opening of the second muntin bar to impede separation of the clip from the second muntin bar; b) a first muntin bar engagement leg extending from one end of said flat, thin body; and c) a second muntin bar engagement leg extending from an end of said flat, thin body opposite to said one end; d) said muntin bar engagement legs extending along a longitudinal axis of said joiner clip.
