1. A pipe connection apparatus comprising:
an outer body having a pipe mount part having a pipe insertion space opened rearward so that a pipe end is inserted into the pipe insertion space; and
a swaging ring configured to come into contact with and press at least a part of the pipe mount part while surrounding at least a part of the pipe mount part,
wherein the pipe mount part comprises:
a first swaged portion having a first inner protruding portion;
a second swaged portion having a second inner protruding portion and positioned to be spaced apart forward from the first swaged portion at an interval;
a connection portion configured to connect the first swaged portion and the second swaged portion;
a front extension portion extending forward from the second swaged portion; and
a rear extension portion extending rearward from the first swaged portion and having a rear outer protruding portion,
wherein the swaging ring comprises:
a first ring portion having a first ring inner diameter larger than an outer diameter of the pipe end;
a first tapered portion extending forward from a front end of the first ring portion so that an inner diameter thereof increases forward;
a second ring portion positioned forward of the first tapered portion and having a second ring inner diameter larger than the first ring inner diameter; and
a second tapered portion extending forward from a front end of the second ring portion so that an inner diameter thereof increases forward; and
an inner groove portion configured to connect the first tapered portion and the second ring portion and recessed outward further than a front end of the first tapered portion and a rear end of the second ring portion, and
wherein the inner groove portion engages with the rear outer protruding portion to restrict a rearward movement of the swaging ring in a state in which components are completely assembled so that an inner peripheral surface of the second ring portion is in contact with an outer peripheral surface of the first swaged portion, the components being the second ring portion and the first swaged portion.
