A sash (4) has an elongate framing member (5, 6) and an elongate retainer (30) for holding a glazing assembly (20) in a rebate (8) in the framing member. The framing member and retainer each have generally constant transverse cross-sections. The retainer has opposite longitudinal sides (31, 32) and a longitudinal intermediate portion (33) which includes a projection (50). The first side cantilevers over the rebate in the framing member. The projection has an L-shaped cross-section with a distal limb that extends toward the cantilevered first side for interlocking the retainer with the framing member, such as by engagement with clip (40) mounted on the framing member. The retainer can be secured to the framing member by a fastener (37A) which is inaccessible when the sash is closed in a frame. In a preferred embodiment the retainer and clip are aluminium extrusions and the framing member is made of timber.
