The purpose of the present invention is to provide a plastic fixture (1) for a greenhouse capable of fixating plastic (B) on a frame tightly when a greenhouse (a) is installed. The plastic fixture (1) for a greenhouse of the present invention comprises a main body (2) which is formed into a rectangular shape and has an opening (4) on one side and a receiving space (5) which widens towards the inner side of the opening (4) and a fixing spring (3) which is elastically combined to the opening (4) of the main body (2) and is formed of a plate spring to fixate the plastic (B) to the main body (2). A cylindrical separation preventing unit (6) which is bent to be protruded to the inner side is formed on both sides of the opening (4) of the main body (2). The fixing spring (3) includes an elastic unit (7) which is curved at the center and is stretched long. A cylindrical holding unit (8) which is bent to the top inner side is formed on both sides of the fixing spring (3). The fixing spring (3) is elastically combined to the opening (4) of the main body (2) and the plastic (B) is fixated to the main body (2). The both holding units (8) of the fixing spring (3) are hung on the both separation preventing units (6) of the main body (2). According to the present invention, the plastic (B) can be fixated stably and a fixing work of the plastic (B) is simply rapidly executed. Corrosion is prevented and the durability of the plastic fixture (1) is improved and the damage in which the plastic (b) is ripped is prevented. Therefore, the plastic can be used for a long time.COPYRIGHT KIPO 2014본 발명은 비닐하우스(A)를 설치할 때 골조 등에 비닐(B)을 긴장된 상태로 고정할 수 있도록 한 비닐하우스용 비닐고정구(1)를 제공코자 하는 것으로서, 상기 본 발명의 비닐하우스용 비닐고정구(1)는 개략 ㄷ자 형태로 일측에 개구부(4)를 가지면서 개구부(4) 내측으로 넓어지는 수용공간(5)을 갖는 본체(2)와, 본체(2)의 개구부(4)에 탄성 결합되면서 비닐(B)을 본체(2)에 고정시키도록 판스프링으로 이루어진 고정스프링(3)으로 이루어지되, 상기 본체(2)에서 개구부(4)의 양측에는 내향 돌출되게 벤딩으로 형성된 원통형의 이탈방지부(6)가 구비되며, 상기 고정스프링(3)은 가운데에 상향 만곡지며 길이방향으로 길게 뻗은 탄성부(7)가 구비되면서 고정스프링(3)의 양측으로 상향 내측으로 벤딩으로 형성된 원통형
