ABSTRACT:
A quick-release joint for two tubes which includes a first connector having a first inner lip formed on an inner surface of the first connector, a second connector pivotally connected to the first connector and axially offset from the first connector. The second connector has a protrusion formed on an inner surface of the second connector and has an outer groove formed on the protrusion next to a top face of the second connector to correspond to the first flange. A retainer is formed on a side of the first connector and the second connector to move the first connector to axially align with the second connector such that after the first inner lip is received in the outer groove of the protrusion, the first connector and second connector are solidly and rigidly coupled.
