A chuck device for use with a flexible hose including a porting tube means for attachment at one end to a source of hydraulic fluid and having a central passage for the fluid. Attached on the other end of the porting tube is a seal cartridge means which has a hose engaging cylinder extending away from the porting tube to engage the interior of the hose. Collet means are mounted on the cartridge means and are positioned to engage the exterior of the hose when the hose is on said cylinder. A chuck body means is included which is slideably mounted on the porting tube and the cartridge means to define a power chamber. The porting tube has a fluid passage connecting the power chamber to the central passage of the porting tube. Finally, nose cone means are mounted on the body means and has a collet means engaging surface. The passage of fluid into the chamber forces the collets against the surface and causes them to urge the collets against the hose. The flexible hose is then tightly grasped on the inside and the outside and, as additional fluid pressure is employed, the grip becomes stronger.
