interconnecting the second vertical member to the first vertical member, and locking means for securing the position of a first part of the, or each, link relative to a second part of the, or each, link, the locking means comprising a releasable snap clamp that has a base secured to the first part and has an arm that carries a clamping member that can engage the second part of each link and clamp onto the second part and thereby lock them together.

2. A frame according to claim 1 wherein there are two horizontal links that define the upper and lower extremities of the opening respectively.

3. A frame according to claim 1 or claim 2 wherein the, or each, horizontal link comprises two parts, one of which is moveable relative to the other to vary the length of the horizontal link.
