The main purpose of the present invention is to provide a fixedly insert-type pipe connecting apparatus with which pipes can be both connected and separated, and which resolves structural issues of the conventional fixedly insert-type pipe connecting apparatus, while, at the same time, allowing the unit cost of production to be significantly reduced. The fixedly insert-type pipe connecting apparatus according to the present invention in order to attain the goal is provided with a pipe connecting main body, into which pipes are inserted, comprising a central section, primary expansions, and secondary expansions, the diameters of which increase stepwise from the middle section to the ends, wherein pipe stoppers for limiting the insertion distance of the pipes are inserted into the central section, O-rings for improving water-tightness and compression springs are inserted into the primary expansions, and into the secondary expansions, ring-shaped jaw tapers having sloped inner circumferential ...
