Each glazing bar has a central load bearing portion (16) which has a solid snapfit formation (22) at one end, interconnected to a solid end portion (23) by a hollow mid-portion (21). A base portion is interlocked with the solid end portion (23) and a clamping section is snap-fitted onto the snap-fit formation (22) so that a respective pane of glazing material can be clamped therebetween. The aligned pair of glazing bars are connected by a key (19) which is placed through a keyhole (18) in the intervening glazing bar and which extends into the hollow mid-portions (21) of each of the aligned pair. The keyhole (18) is formed solely through the hollow mid-portion (21) of the glazing bar, and the key (19) is inserted through the aperture (18) and then rotated and snap-fitted into a locked setting. |
