Fitting connection for high-pressure hoses

A connection assembly for a hose for conveying a fluid under a fluid pressure, the hose having a hose end, and the assembly comprising:

• a fitting comprising:
• a generally tubular nipple extending along a longitudinal axis intermediate a first nipple end portion insertable in the hose end and a second nipple end portion;
• a fitting flange surrounding the nipple between the first and the second nipple end portion thereof, the fitting flange extending radially outwardly and having a forward face adjacent the second nipple end portion and an opposite rearward face;
• and
• a generally tubular sleeve disposed coaxially over the first nipple end portion, the sleeve having an inner sleeve surface radially spaced-apart from the first nipple end portion to define a generally annular space therebetween for receiving the hose end of the hose as the first nipple end portion is inserted thereinto, the sleeve being pressable onto the hose for retaining the hose end on the first nipple end portion;
• a generally annular connector extending between a first connector end and a second connector end, the second nipple end portion being slidably receivable coaxially in the first connector end;
• and
• a generally tubular shell closable coaxially over the fitting, the shell having an internal cavity including a first cavity portion configured to receive the fitting flange therein and a second cavity portion configured to receive at least the first connector end, the first cavity portion having a forward wall and a rearward wall spaced apart axially from the forward wall end, and the shell being divided longitudinal into a first shall half and a second shell half closable with the first shell half to close the shell over the fitting,
• wherein with hose end being inserted into the annular space between the sleeve and the nipple and the sleeve being pressed onto the hose to retain the hose end on the nipple, the second nipple end portion being slidably received coaxially in the first connector end, and the first and second shell halves being closed over the fitting with the fitting flange being received in the first cavity portion with the fitting flange forward face being disposed adjacent the cavity forward wall and the fitting flange rearward face being disposed adjacent the cavity rearward wall, and with at least the first connector end being received in the second cavity, the fitting is slidably movable in the shell responsive to fluid pressure from the hose being received in the connector from a release position wherein the fitting flange rearward face is axially spaced-apart from the first cavity portion rearward face allowing the shell halves to be opened to a locked position wherein the fitting flange rearward face interferingly engages the first cavity portion rearward face preventing the shell halves from being opened.
