ABSTRACT:
Hose coupling devices that securely connect an end of a hose to a fitting member using a retention mechanism operated by multi-threaded engagement of the fitting member with a collar member. The multi-threaded engagement also may operate a hose advancement mechanism. The advancement mechanism axially advances a hose during multi-threaded engagement so that the hose may be more effectively gripped by the retention mechanism.
