<p><P>PROBLEM TO BE SOLVED: To provide a hose connector possible to be manufactured at low cost with small man-hours, though it has a swelling part to be held by a wrench when connecting to other hose. <P>SOLUTION: The hose connector comprises a tubular core metal formed with a hose insert part, in which a hose is to be inserted, in one end thereof and formed with a screw part to be connected to other hose in the other end thereof or having a nut arranged therein, a fastener provided to surround the hose insert part to fasten the hose by crimping toward the center of the core metal in the state of inserting the hose into the hose insert part, and a wrench holding metal installed in the core metal by fitting it in a position adjacent to the other end of the hose insert part so that a wrench is put on the peripheral surface thereof when connecting to other hose. The wrench holding metal is fixed by crimping the fastener so as to prevent rotation thereof in relation to the core metal. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
