ABSTRACT:
A collapse resistant hose is described which may be selectively deformed to a desired shape. It includes the usual elongated polymeric body, including an internal passageway in which is positioned a spring insert reinforcement. An axially extending rod means is positioned adjacent the spring to which it is intimately attached, permitting the hose to be deformed to a desired shape-retaining configuration by bending the rod beyond its yield point.
