Claim:
A window assembly comprising, in combination: a glazing; a frame encircling a periphery of the glazing and securable about an opening in a support structure; at least one retaining bracket secured to the glazing; wherein the retaining bracket has at least one tab forming an interlock with the frame to secure the glazing to the frame so that the glazing is selectively removable from the frame without removing the frame from the support structure; wherein the retaining bracket extends through an opening in the frame with the glazing located on a first side of the frame and the tab located on a second side of the frame opposite the first side; wherein the retaining bracket is formed of sheet metal and the tab is a bent tab; wherein the retaining bracket includes a vertical portion secured to the glazing, a flange perpendicularly extending from the vertical portion at an edge of the glazing, and a horizontal portion perpendicularly extending from the vertical portion and through the opening in the frame; wherein the tab extends from the horizontal portion with a bend perpendicular to the face of the glazing; and wherein the tab is sized and shaped to pass through the opening in the frame in either direction prior to being bent to form the interlock with the frame and to prevent passage through the opening in the frame in either direction after being bent to form the interlock with the frame so that the tab is passed through the opening in the frame and then plastically bent to form the interlock with the frame to secure the glazing to the frame.
