The invention relates to a locking device for a sash (30) of a hung sash window, said slash sliding vertically in relation to a fixed frame. According to the invention, when the sash (30) is closed, the upper horizontal sash bar (31) is located close to a bar or a strut of a second sash (20) in a parallel manner and can be fixed to the same by means of a displaceable lock element and a lock engaging element (47) which is associated with the bar or the strut (31). The aim of the invention is to provide a locking device which is economically produced and has a structure which is as simple as possible. To this end, the lock element (51) is in the form of a mushroom-shaped pin (51) that can be displaced by means of a driving rod (50) pertaining to a driving rod mounting (48), and the lock engaging element (47) is in the form of a laterally open profiled part which is complementary to the lock element and has an upside down O-(omega)shaped cross-section.

L'invention concerne un dispositif de verrouillage pour un châssis (30) d'une fenêtre à guillotine, ledit châssis coulissant verticalement sur un dormant fixe. Lorsque le châssis (30) est en position fermée, le montant de châssis (31) horizontal supérieur est adjacent et parallèle à un montant ou à un longeron d'un deuxième châssis (20) et peut être fixé, au moyen d'un organe de verrouillage mobile et d'un élément d'emboîtement de verrouillage (47) associé au montant ou au longeron (31), sur ledit élément d'emboîtement de verrouillage. L'objectif de l'invention est de créer un dispositif de verrouillage qui soit conçu de la façon la plus simple possible et qui puisse être fabriqué de manière économique. A cet effet, l'organe de verrouillage (51) est constitué par un tenon (51) en forme de tête de champignon, pouvant coulisser par l'intermédiaire d'une bielle (50) d'une ferrure à bielle (48). En outre, l'élément d'emboîtement de verrouillage (47) est constitué par une pièce profilée, ouverte sur le côté, possédant une forme complémentaire de celle dudit tenon, et présentant une section transversale en forme d'oméga (.OMEGA.) renversé.
