Abstract: Means for jointing a panel partition to an adjoining surface comprises a sole piece in combination with a joint cover member. The sole piece comprises a plastics strip applied to the edge of the partition and has two feet of dovetail form on its outer face which seat against the adjoining surface. On its opposite face the sole piece has seating surfaces and upstanding flanges for engaging the edges and faces of panels and other internal components of the partition. The cover member is an L-shaped metal section which fits externally with the ends of its limbs abutting an exterior panel face and the adjoining surface respectively and it is held in place by an internal rib engaging in a side slot of the sole piece. A supplementary flange locates it against the panel. The arrangement can provide an efficient sealed joint with the adjoining surface even if there are variations in the fitting clearances. Other additional internal elements can also be incorporated.
