<p>The present invention provides a joint connection including a support piece at least one tubular piece and a connector between the support and tubular pieces. The connector includes a first end portion trapped at the support piece, a second end portion fitted in a trap region within the tubular piece and an adjustable connector portion between the first and second end portions of the connecting member. The trap region within the tubular piece is formed by reduced diameter wall regions to either side thereof the inner one of which prevents the second end portion of the connecting member from sliding inwardly along the tubular piece and the outer one of which resists outward pulling of the second end portion for tightening of the connection to firmly secure the joint.</p> |
