A catch device for a pivoting window

The device (1) is suitable for a vehicle window (6) and comprises a first attachment member (2) for fixing to the window, an elongate handle (3) articulated to the first attachment member, a second attachment member (4) for fixing to the vehicle bodywork, and a connecting link (5) connecting the second attachment member to the handle. The length of the link is less than half the length of the handle, and one end of the link is rotatable about an axis (14) in the second attachment member, the other end of the link being rotatable about an axis (13) in the handle which is parallel to the first axis. A locking mechanism (15) acts between the handle and the second attachment member to prevent unauthorised opening of the window. For improved security, the mechanism may pass through an aperture (26) in the handle and into the second attachment member, where it is shielded by sidewalls (43). The locking mechanism may also lock automatically on closure of the window, and preferably requires rotation of a knob (20) to release the mechanism.
