Quick release mechanism for pole mounted mirror

A quick release device for the attachment of a vehicular mirror to a pole, comprising:

• a mounting base for attachment to the mirror, the base having a collar providing threaded engagement with a rotating knob, the knob carrying a stub that moves within the collar;
• the base having a notch for receiving the pole;
• the stub being disposed to clamp the pole against the mirror;
• wherein the knob carries a friction clamp and the collar has external ribs that cooperate with the clamp;
• wherein the external ribs are formed on the exterior of the collar and cooperate with longitudinally arranged teeth formed on the interior of the clamp that releasably engage the external ribs of the collar, so that the engagement of the longitudinally arranged teeth with the external ribs sufficiently frictionally grips the knob to the mounting base to prevent the unscrewing of the knob from the mounting base.
