Product review (5 stars): Quit fighting it and buy one of these now!
Put away the hose clamps and zip ties and buy one of these. It was the simplest dryer hose installation ever. It was literally everything I have ever wanted in a dryer vent connection : easy installation and doesnt come off when pushing the dryer back in. Nothing to screw in, nothing to hold in place while moving the dryer back in place. Add in the solid construction and great design allowing it to push right up against the wall, this is the vent connector you are looking for.
