Abstract: A muntin clip comprises a base having an interior face and an opposed exterior face. The interior and exterior faces extend between a first end positionable towards the first glazing pane and a second end positionable towards the second glazing pane. A muntin connector extends from the interior face. The muntin connector comprises a tongue receivable within the muntin bar and frictionally securable therein. A seal connector extends from the exterior face. The seal connector comprises a side plate positionable between the seal and the first glazing pane. The side plate has an inner face positionable to face the seal and an opposed outer face. At least one tooth extends from the inner face. The at least one tooth is insertable into the seal.

Abstract: A sliding shoe for a sliding/pivoting window having a shoe body which is of two piece construction. A cam trapped between the two portions of the shoe has a cam-shaped body, which rotates in complementary cam-shaped openings through the shoe portions to expand the shoe laterally, and a chamfered cam-shaped annulus which rotates in a complementary bevelled seat in the shoe body to expand the shoe in a direction perpendicular to the lateral expansion. The shoe is thus locked in position in the frame channel very early in the rotational cycle of the cam, and provide secure locking engagement against the sides, top and bottom of the channel when the sash is pivoted only slightly out of the plane of the frame.
