Abstract
A connection assembly is particularly useful for positively connecting a flexible hose member with an inlet plug for a suction source while being adapted for subsequent disconnection without requiring any specialized tools. In connecting operation, an integral extension portion of a flexible hose member is telescopically inserted into an inlet plug to a predetermined longitudinal stopping point therein, and then rotated so as to cause engagement of projections formed on the extension portion and projection-receiving holes formed in the inlet plug. Such engagement rotatably and longitudinally secures the flexible hose relative the inlet plug. Slots are formed in the inlet plug for guiding the hose member projections during longitidinal movement of the hose member. The hose member may be selectively withdrawn by reverse rotation of the hose extension portion and longitudinal removal thereof from the inlet plug. During such reverse rotational movement, a camming surface is used to assist withdrawal of projections from their respective holes for disengaging same without requiring special tools.
