A security device or an assembly including a security device comprising two parts which are intended to be attached to the hinged edge of a hinged panel. The first part (10) having a projection (14) with a flanged formation (17) on at least one edge, and the second part (20) having a ledge (28) in which is formed a 'key hole' shaped aperture (22) having first (25) and second (26) portions. The second portion (26) being of a smaller diameter than the first (25). When the hinged panel is brought into contact with the frame the projection (14) on the first part (10) is received in the first portion (25) of the 'key hole' shaped aperture (22). Any attempted lateral movement of the wing away from the frame will cause the projection (14) to pass through into the smaller portion (26) of the aperture (22) and cause the two parts (10,20) to combine to resist any further movement. |
