Abstract
Disclosed is an improved handle for a clothing steamer which solves the problem of steam delivery hose working free of a barbed fitting. The handle is fitted with a plurality of protrusions that impinge the outer diameter of the hose, thereby securing it in place through friction with the protrusions and also by forcing the inner diameter of the hose against the barbs of the barbed interference fitting.
