ABSTRACT:
A stopcock comprises a hollow barrel which receives in a rotatable manner a co-operating tap. A section of the tap is formed with holes which allow communication between selected hollow spigots extending from the barrel. A further section of the tap of larger diameter than the section is formed with indents which engage with detents formed on a large diameter section of the barrel to provide a positive indication when the tap is rotated within the hollow barrel to one or more selected positions.
