Claims (1)

[Claims for Utility Model Registration] 1. Receive the tip of a flexible fluid piping hose and lock and hold the tip of the hose so that it communicates with the internal passageway of the socket while airtightly sealing the gap with the outer periphery of the hose. A socket for fluid piping, the main body having a socket opening at an end that communicates with the internal passage, and a socket coaxially in contact with an inner circumferential wall of the socket opening to airtightly seal a gap between the outer periphery of the hose. an annular seal member disposed therein; and a locking ring member mounted within the socket opening at a position closer to the socket opening end than the annular seal member so as to be relatively rotatable and prevented from relative axial movement. The locking ring member is configured to allow the distal end of the hose to be inserted into the socket opening through the inner hole of the locking ring member, and to prevent the hose from being removed in the opposite direction by engaging with the outer peripheral surface of the hose. A fluid piping socket characterized in that a plurality of blocking engagement protrusions are provided obliquely protruding toward the inside of the socket opening toward the socket axis. 2. The socket for fluid piping according to claim 1, wherein the locking ring member is made of a spring metal split ring that is cut at a portion in the circumferential direction of the ring so as to be able to expand or contract in diameter. 3. A fluid pressure utilization tool, characterized in that the fluid piping socket according to claim 1 or 2 is provided at a pressurized fluid intake port.
