Abstract
Structure for concurrently connecting an end of a vacuum cleaner hose to a canister suction inlet and an electrical power cord carried exteriorly of the hose and having at one end a first electrical connector associated with the hose end to a complementary second electrical connector associated with the canister. The connecting structure includes locking structure formed integrally with the hose end for releasably locking the hose end to the suction inlet to provide an air flow connection therebetween. Mounting structure is formed integrally with the hose end for removably mounting the first electrical connector to the hose end to be accurately aligned and engaged with the second electrical connector as an incident of locking association of the locking means to the suction inlet.
