Abstract: A latch assembly for installation in a recess along a side edge of a wing element, for covering or uncovering an aperture, the latch assembly being adapted to hold the wing element in a closed position. The assembly includes a housing having at least one wall, at least one espagnolette bolt and an espagnolette rod. The espagnolette bolt is slidingly arranged in the housing between a first open position, in which the espagnolette bolt is retracted into the housing, and a second latching position, in which the espagnolette bolt projects from the housing to engage with a catch. The espagnolette bar is operatively connected to the espagnolette bolt for maneuvering the espagnolette bolt between the first open position and the second latching position. A latching pin is arranged for displacement with the espagnolette bolt, during movement of the espagnolette bolt from the first open position to the second latching position and back.
