Abstract
The diffuser connector includes an elastic base part which is in the form of a tube adapted to be inserted into a round opening formed in the air header pipe wall. The connector also includes a rigid insert having a stem which, when pushed through the base, flares the tube to form a grommet which secures the base to the pipe. A cooperating detent means between the base and the insert at the same time secures the latter to the base. The connector provides the quick securement of the diffuser to the pipe with the required air seal therebetween and does not require threading or any other finishing of the pipe opening. The diffuser may comprise separable parts, one of which includes the insert and the other includes the air outlets.
