<p>A frame has at least two rods (2a, 2b) which are connected spaced from each other by a connector (3) having a locking bolt (7) and expanding device (C). The locking bolt (7) is clip shaped and fits at the top end (B) into a rear cut groove of one rod (2b) and at the bottom (A) into an end cavity (17) of the other rod (2a). The locking bolt (7) can be U-shaped. The expanding device (C) has an eccentric bolt (8a) which between the two rods (2a, 2b) spreads open the two arms (7a, 7b) of the locking bolt across the longitudinal direction and thereby detachably connects the relevant ends (B, A) of the locking bolt (7) by clamping action to the associated rod (2a, 2b).</p> |
