ABSTRACT:
A hose coupling assembly (10) of the type adapted to secure a hose (12) to a fitting. The assembly (10) includes a hose (12). A coupling member (16) is provided which includes an insert portion (18) for disposition within an opening (14) in the hose (12). An inner collar (28) is positioned about the exterior of the hose (12) and radially spaced from the insert portion (18) of the coupling member (16). An outer collar (38) is positioned over the inner collar (28) to provide an inwardly directed force thereto. The inner collar (28) has a plurality of slots (34) therein. The slots (34) compress in response to the inwardly directed force from the outer collar (38) to reduce the inner diameter of the inner collar (28) to thereby provide radial compression completely about the hose (12). The compression prevents removal of the coupling member (16) from the hose (12).
