A system for securing a side glazing of a means of transportation, in particular a train glazing, to a peripheral bodywork opening, said system comprising a glazing and a peripheral bodywork opening; said glazing being a fixed multiple glazing having an external face which faces an external space and an internal face which faces an internal space, said external face of the glazing being continuous in appearance with an external face of said bodywork opening over its entire periphery, said glazing comprising: - an external pane having an external face which faces the external space and a peripheral edge, said external pane preferably being laminated and then comprising at least one external glass sheet, an internal glass sheet, and a plastic sheet located between said external glass sheet and said internal glass sheet, each sheet (3, 4, 5) of said external pane having a peripheral edge (30, 40, 50), - an internal pane having an internal face which faces an internal space, an intermediate face opposite the internal face, and a peripheral edge, - an inner structure which is located at the inner periphery of said external pane and at the inner periphery of said internal pane being more toward the center than the peripheral edge (20, 60) of said external pane and said internal pane respectively, and which holds these two panes together such that the glazing provides a separation between said external space and said internal space with a glazing cavity located between said panes (2, 6), said inner structure comprising a hooking cavity having a centripetal bottom and a centrifugal opening, said bodywork opening comprising an internal flank having an attachment hole which is located more centrifugal than said edge of said internal pane and having an axis parallel to said edge of said internal pane, a latch is secured to said internal flank by an attachment means passing through said attachment hole, characterized in that said latch has a lateral wing extending within said hooking cavity and opposite an edge of said intermediate face of the internal pane by rotating said lateral wing through 90°. said glazing comprising: - an external pane having an external face which faces the external space and a peripheral edge, said external pane preferably being laminated and then comprising at least one external glass sheet, an internal glass sheet, and a plastic sheet located between said external glass sheet and said internal glass sheet, each sheet (3, 4, 5) of said external pane having a peripheral edge (30, 40, 50), - an internal pane having an internal face which faces an internal space, an intermediate face opposite the internal face, and a peripheral edge, - an inner structure which is located at the inner periphery of said external pane and at the inner periphery of said internal pane being more toward the center than the peripheral edge (20, 60) of said external pane and said internal pane respectively, and which holds these two panes together such that the glazing provides a separation between said external space and said internal space with a glazing cavity located between said panes (2, 6), - an external pane having an external face which faces the external space and a peripheral edge, said external pane preferably being laminated and then comprising at least one external glass sheet, an internal glass sheet, and a plastic sheet located between said external glass sheet and said internal glass sheet, each sheet (3, 4, 5) of said external pane having a peripheral edge (30, 40, 50), - an internal pane having an internal face which faces an internal space, an intermediate face opposite the internal face, and a peripheral edge, - an inner structure which is located at the inner periphery of said external pane and at the inner periphery of said internal pane being more toward the center than the peripheral edge (20, 60) of said external pane and said internal pane respectively, and which holds these two panes together such that the glazing provides a separation between said external space and said internal space with a glazing cavity located between said panes (2, 6), said inner structure comprising a hooking cavity having a centripetal bottom and a centrifugal opening, said bodywork opening comprising an internal flank having an attachment hole which is located more centrifugal than said edge of said internal pane and having an axis parallel to said edge of said internal pane, a latch is secured to said internal flank by an attachment means passing through said attachment hole, characterized in that said latch has a lateral wing extending within said hooking cavity and opposite an edge of said intermediate face of the internal pane by rotating said lateral wing through 90°.
