<p>Supporting hooks or attachments for fmetal tubes forming part of gymnasium equipment are secured by two clamps (1, 2) made from a steel ring. The clamps are held on the bar by two simple cable connectors (3, 4). This is done without soldering or screwing and so avoids weakening the metal. Cross bars can be supplied already assembled with this fixing and the equipment can be easily modified for a new use. The fixing can be used separately to assemble new cross bars on the modify one.</p> |
