ABSTRACT:
A hose coupling member comprises a housing with a through opening and with grooves oriented obliquely along the inner surface of the housing, a piston arranged in the housing to seal the through opening, a shaft attached to the piston, and an actuator arranged inside housing. Upon relative rotation between housing and the actuator shaft will run in grooves and establish a linear relative movement between the housing and the piston, the actuator being arranged and shaped so that the actuator acts directly upon the shaft. Rolls are preferably mounted on the shaft.
