Abstract
A blower/vacuum device has removable blower tube configured to connect with a connector stub of the device. The connector stub has a guide path formed in its interior wall and the blower tube has a latch runner disposed on its outer surface. A flipper is positioned in the guide path near the end of the circumferential segment of the guide path and coacts with the latch runner. The flipper is biased such that its tongue extends into the guide path. When the blower tube is rotated a sufficient distance such that the latch runner is rotated past the tongue, the flipper is repositioned by spring force and the tongue locks the blower tube in place. The flipper is repositioned to move the tongue out of contact with the latch runner to permit the blower tube to be rotated in the disconnect direction and removed from the connecting stub.
