The present invention relates to a connection device for a washstand drainage pipe and, more specifically, to a connection device installed in a lower part of a discharge pipe installed in a waterspout of a washstand to discharge water to a washstand and to which a sewage pipe is coupled to deliver discharged water. The present invention provides a connection device for a washstand drainage pipe, wherein the connection device comprises: a connection pipe part which has a connection pipe fitted to a lower part thereof, has a screw part formed on an upper inner circumference thereof to fasten the discharge pipe to the upper part thereof, has hanging protrusions protruding from an outer surface thereof, and has a ring-shaped flange part formed on an outer peripheral surface of an upper side thereof; a fixing cap part which is fitted to the flange part, has a hanging projection part formed on a lower surface of the flange part to be hung, and has a through hole formed therein to communicate with the connection pipe part so that the discharge pipe penetrates therethrough; and an elastic sealing unit formed on an upper portion of the fixing cap part, having a connection hole formed therein to communicate with the through hole so that the discharge pipe penetrates therethrough, and having an annular elastic sealing panel formed on an upper inner circumferential surface of the connection hole to press the fitted discharge pipe. The connection device for a washstand drainage pipe according to the present invention fastens a fixing cap part to a connection pipe part coupled to a drainage pipe of a washstand, and an elastic sealing unit, which is made of a synthetic resin material having elasticity on an upper portion of a fixing cap part, is formed to press a drainage pipe and maintain water tightness. Thus, the elastic sealing unit is formed in a stacked structure, and space utilization is facilitated. Since the structure is simple, manufacturing is facilitated, and manufacturing costs are reduced. 본 발명은 세면대 배수관용 연결장치에 관한 것으로서, 보다 상세하게는 세면대에 물을 배출시키도록 세면대의 통수구에 설치되는 배출관의 하부에 설치되고, 배출되는 물을 전달하도록 하수관이 체결되는 연결장치로서, 연결관이 하부에 끼움되고 상부에는 상기 배출관이 체결되도록 상측 내주연에 나사부가 형성되고 외면에 돌출되게 걸림돌기들이 형성되며 상측 외주연에 환형의 플랜지부가 형성된 연결관부; 상기 플랜지부에 끼움되고 상기 플랜지부의 저면에 걸림되도록 걸림턱부가 형성되며, 상기 배출관이 관통되도록 상기 연결관부와 연통되게 관통공이 형성된 고정캡부; 및 상기 고정캡부의 상부에 형성되며 상기 배출관이 관통되도록 상기 관통공과 연통되게 연결공이 형성되고, 상기 연결공의 내주연 상부는 끼움된 상기 배출관을 가압하도록 환형의 탄성실링패널이 더 형성된 탄성기밀유닛으로 이루어진 것을 특징으로 하는 세면대 배수관용 연결장치를 제공한다. 본 발명인 세면대 배수관용 연결장치는 세면대의 배수관에 체결되는 연결관부에 고정캡부를 체결하고, 고정캡부의 상부에 탄성을 갖는 합성수지재로 이루어지고 배수관을 가압하여 수밀을 유지시키는 탄성기밀유닛을 형성시킴으로써, 적층구조로 탄성기밀유닛을 형성시켜 공간활용이 용이하게 되고, 구조가 간단하여 제조가 용이하며 제조비용이 절감되는 효과가 있다.
