Abstract
Abstract A support for a cylindrical block of deodorizer product is in the form of a cylindrical cage formed of two identical parts each of which has a cylindrical shape with a closed end and an open end defined by an end collar, the end collars of the two parts being interengageable by means of male and female engagement means carried by both end collars for rendering the two cage parts integral as a single cylindrical cage. The suspension hook is integrally formed with a connection sleeve which has a larger diameter portion capable of engaging on the end collars of the two cage halves and a smaller diameter portion capable of engaging on and sliding along either cage half over a portion other than the said end collar thereof and the narrower diameter portion includes catch engagement means for permitting sliding engagement of the connecting sleeve along the cage in one direction only.
