Abstract
Abstract An adapter for connecting one size of nozzle with a blower tip of varying sizes has a plurality of springs spaced there around. Each spring has straight portions resiliently urged towards the blower tip. At the entrance end of the adapter, the springs are sloped or tapered so the blower tip will gradually flex the springs towards the wall of the adapter. The springs may be solid, like leaf springs, or may be formed of wire; and, the springs may be made of polymeric material, metal or other elastic materials. In other embodiments, the springs may be fixed to the male member for receiving a female member thereon; and, the male or female member may have a slope rather than the springs. The spring members may have two straight portions parallel to each other, or only one straight portion.
