<p>A sub-assembly for use as a rail or frame element in a room-divider or panel system comprises a rail member (30) having a recess (32) formed therein. The recess (32) is of a shape such that it is engageable with a hook member (10) of a first kind to secure an object carried by the hook member (10) to the rail member (30). An insert member (40) locatable in the recess (32) of the rail member (30) changes the cross-sectional shape of the recess in the rail member (30) such that it is engageable with a hook member (20, 60) of a second kind to secure an object carried by that hook member to the rail member.</p> |
