A glazed closure for an opening comprising: at least one frame element; at least one glaze assembly comprising at least one glaze, and at least one support element; at least two inserts (260; 260A-260D) affixed to the at least one glaze assembly; and at least two fastening elements (270; 270A-270D) to fasten said at least one frame element to said at least two inserts (260; 260A-260D) and to fasten said at least one frame element to said at least one glaze assembly to prevent detachment movement of said at least one frame element relative to said glaze assembly; said inserts being spaced apart from each other and each comprising a cavity receiving an end of one of said fastening elements (270; 270A-270D) and being shaped as an elongated conduit having its longitudinal axis parallel to the proximal edge of said at least one glaze; and wherein said at least one frame element has at least two apertures each receiving one of said at least two fastening elements inserted through said at least one frame element and into said cavity in one of said at least two inserts fastening said at least one frame element to said glaze assembly in a direction parallel to the plane of said at least one glaze and perpendicular to a plane tangential to the edge of said at least one glaze proximal to one of said at least two fastening elements, said glazed closure being characterised in that the elongated conduit of said inserts has a fastening formation in its internal profile adapted to provide fastening holding to the corresponding fastening element (270; 270A-270D) to be affixed to said at least one glaze assembly to allow sliding movement of said fastening element (270; 270A-270D) along the longitudinal axis of said elongated conduit within said cavity without diminishing its resistance to detachment movement caused by pulling-out forces, to allow sliding movement of said at least one frame element relative to said glaze assembly. at least one frame element; at least one glaze assembly comprising at least one glaze, and at least one support element; at least two inserts (260; 260A-260D) affixed to the at least one glaze assembly; and at least two fastening elements (270; 270A-270D) to fasten said at least one frame element to said at least two inserts (260; 260A-260D) and to fasten said at least one frame element to said at least one glaze assembly to prevent detachment movement of said at least one frame element relative to said glaze assembly; said inserts being spaced apart from each other and each comprising a cavity receiving an end of one of said fastening elements (270; 270A-270D) and being shaped as an elongated conduit having its longitudinal axis parallel to the proximal edge of said at least one glaze; and wherein said at least one frame element has at least two apertures each receiving one of said at least two fastening elements inserted through said at least one frame element and into said cavity in one of said at least two inserts fastening said at least one frame element to said glaze assembly in a direction parallel to the plane of said at least one glaze and perpendicular to a plane tangential to the edge of said at least one glaze proximal to one of said at least two fastening elements, said glazed closure being characterised in that the elongated conduit of said inserts has a fastening formation in its internal profile adapted to provide fastening holding to the corresponding fastening element (270; 270A-270D) to be affixed to said at least one glaze assembly to allow sliding movement of said fastening element (270; 270A-270D) along the longitudinal axis of said elongated conduit within said cavity without diminishing its resistance to detachment movement caused by pulling-out forces, to allow sliding movement of said at least one frame element relative to said glaze assembly.
