High-pressure fluid hose connector

A high-pressure fluid hose connector, comprising:

• a longitudinally extended connecting pipe with an upper portion having an annular shoulder formed thereon, a middle portion having a plurality of longitudinally extended teeth defined on an outer periphery thereof in angularly spaced relationship, and a lower portion having multiple gripping flanges on the outer periphery thereof;
• an upper sleeve co-axially fit on the connecting pipe, said upper sleeve having a lower portion with a flange extending therefrom to engage the annular shoulder of the connecting pipe when fit on the connecting pipe, the upper sleeve being adapted to connect to a union;
• a locking sleeve co-axially fit on the connecting pipe, the locking sleeve having a plurality longitudinally extended notches formed on an inner periphery thereof in correspondence with the plurality of teeth of the connecting pipe, and having a lower portion defined thereon;
• a lower sleeve co-axially fit on the connecting pipe, the lower sleeve having multiple gripping flanges formed on an inner periphery thereof and an upper portion adapted for locking on the lower portion of the locking sleeve;
• and,
• a gap formed between the gripping flanges of the upper sleeve and the lower sleeve to securely receive a hose therein;
• wherein the plurality of teeth are respectively locked together with the plurality of notches to prevent rotation of the connecting pipe relative to the lower sleeve so that the hose is prevented from being scraped by the gripping flanges during installation of the connector with a union.
