[ We claim:] [1.]1. A muntin grid that includes a muntin bar joiner detachably joining three muntin bars, the grid comprising:a first tubular muntin bar having oppositely facing sides that form outwardly facing grid surfaces and an elongated narrow through opening that extends transverse to the first muntin bar, second and third tubular muntin bars that extend transverse to said first muntin bar, each of said second and third muntin bars having oppositely facing sides that form outwardly facing grid surfaces and an open end that abuts said first muntin bar, each said open end surrounding said through opening;a flat, thin joiner body having a longitudinal axis with opposite edges extending in the direction of said axis and opposite sides defining major faces, said joiner body extending transverse to said first muntin bar through said through opening;a first leg projecting from said body and telescoping into the second muntin bar, said first leg engaging the second muntin bar to maintain said second muntin bar aligned with said axis in fixed relationship with said joiner;a second leg projecting from said body and telescoping into said third muntin bar, said second leg engaging the third muntin bar to maintain said third muntin bar aligned with said axis in fixed relationship with said joiner;first and second abutments extending from said body in a direction transverse to said axis, each abutment comprising an abutment face oriented in a direction transverse to said axis for engaging said first muntin bar and locking said joiner and said second and third muntin bars in position with respect to said first muntin bar, said abutment faces facing in opposite axial directions with one of said abutments comprising a wedge-like ramp for making latching engagement with said first muntin bar.
