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.

A handpiece for a portable clothing steamer comprising:
- a steam head portion defining one or more openings at one end thereof;
- a barbed hose fitting integral with said steam head portion;
- a rubber hose fitted over said barbed hose fitting;
- a first handle piece defining one or more protrusions on the inner surface thereof;
- and
- a second handle piece defining one or more protrusions on the inner surface thereof;
- wherein said protrusions defined on the inner surfaces of said first and said second handle pieces comprise:
- a first group of protrusions disposed such that they contact a portion of said hose having said barbed fitting disposed therein;
- and
- a second group of protrusions disposed such that they contact a portion of said hose not having said barbed fitting disposed therein;
- wherein said second group of protrusions is longer than said first group of protrusions;
