Abstract
A hose end assembly comprises an adaptor (30) connected to one end of a cable conduit hose (10) for containing liquid medium. The adaptor comprises a body (32) having a barbed extension (44) and a retaining means such as a sleeve (34). The hose is pushed over the barbed extension, and then the sleeve is forced over the hose by means of a jack (60, FIGS. 2 and 3) to compress the hose between the sleeve and the extension. The body and the sleeve can have axially facing bearing surfaces in the form of recesses (42, 50) for engaging with projections on the jack. The sleeve can have internal projections (46, 48) to further compress the hose, and the sleeve and the hose can be in electrical contact with each other. A bend restrictor (90, FIG. 4) can be provided to limit the bending of the hose. The invention also extends to the use of an assembly to form a termination of a cable conduit hose containing liquid medium.
