ABSTRACT:
This invention provides an improved adjustable tube clamping connector, especially one used for making adjustable connection of an inner tube and outer tube as required by the actual conditions. The outer tube has an open slot and is attached by welding to a clamp with two lugs on the slot. Fitted in the cavities of the lugs are a pair of clamping pieces each of which has a pair of extensions with curved surfaces. With the back of the clamp pieces against the bottom of the cavities of the lugs and the curved surfaces of the extensions on the external surface of the outer tube, they will give added strength and pressure to make the outer tube firmly grip and hold the inner tube so as to bear greater load and to ensure safe use.
