Figure 3b is a view of Figure 1b with the engaging links disengaged,

Figures 4a and b are enlarged views of the clamp in the open position;

Figures 5a and b are enlarged views of the engaging links engaged and disengaged respectively;

Figure 6 is a further enlarged view of the engaging links;

Figure 7 and 8 are side views of the engaging links partially and fully engaged, respectively.

BEST MODE FOR CARRYING OUT THE INVENTION

In Figure 1(a), a pendant 10 is shown suspended from a chain 12. The. pendant comprises an elongated element 14 comprising a series of links 16. End link 18 comprises a clamp 20 which closes over the chain 12 to enable it to be suspended therefrom.

Release of the clamp 20 from the chain 12 (Figure 3a) allows the elongated element 14 (Figures 2a and b) to be converted to a ring 22 as shown in Figure 2b. A groove 24 is provided to assist in opening the clamp. The clamp 20 comprises a pair of hinged jaws 26a and b each of which comprises half the thickness of the end link 18. The inner, abutting surfaces 28, 30 (Figure 4) of the jaws include a groove 32, which register to form a slot 34 which encircles the chain 12 when the Figure 2(b); clamp is closed. A locking lug 36 (Figure S(a), Figures 7 and 8) is provided to assist in preventing the clamp form opening accidentally.

In order to form a ring 22 or even a bracelet, should the elongated element have sufficient length, engaging end link 18 and receiving end link 38 must be engaged. The engaging link 18 includes a T-shaped formation 40 pivotally mounted on the hinge 42 of the end link 18. Receiving end link 38 includes a T-shaped recess 44 with the stem of the T comprising a wide channel 46 having overhanging flanges 48 either side along its length to enable the arms of the T to be slided thereunder to reach the engaged position shown in Figures 5(b) and 8. The T-formation 40 is slided in the direction of the arrow in Figure 7, to reach the position shown in Figure
