The present invention relates to a clip for fixing a plastic sheet covering the frame of a greenhouse, which comprises pressing parts (12, 13) formed on both sides of a main body (11) curved parts (12a, 13a) formed at lower parts on both sides of the pressing parts (12, 13) a hollow part (14) formed on the inner surface of the main body (11) and an open part (15) formed on one side of the hollow part (14). In particular, steel wires (22, 23) are inserted in and thereby coupled to coupling grooves (20, 21) of reinforcing protrusions (16, 17) formed on both sides of the outer surface of the main body (11) to reinforce strength of the main body (11), thereby improving the overall strength including the main body (11) a plastic sheet (30) is reliably and securely pressed the steel wires (22, 23) are prevented from separating, by means of catching projections (16a, 17a) formed on one outer side of the coupling grooves (20, 21) the overall strength is further improved by means of a plurality of reinforcing parts (26, 27, 28) formed in a width direction of the inner and outer surfaces of the main body (11) the steel wires (22, 23) can be easily inserted (coupled) into the coupling grooves (20, 21) by using planar parts (18, 19) formed on both sides of the main body (11) and by using handles (24, 25) formed on both sides of the main body (11), the plastic sheet (30) can be easily and conveniently pressed and thereby affixed to a frame (29), or a plastic sheet-fixing clip (10) affixed to the frame (29) can be easily separated.본 발명은 비닐하우스의 골조에 씌워지는 비닐을 고정시키는 클립(clip)에 관한 것으로, 본체(11) 양측에 형성되는 압지부(12)(13)와, 압지부(12)(13) 양측 하부에 형성되는 만곡부(12a)(13a)와, 본체(11) 내면에 형성되는 중공부(14)와, 중공부(14) 일측으로 형성되는 개방부(15)를 포함하되, 상기 본체(11) 외면 양측에 형성되는 보강돌부(16)(17)의 결합홈(20)(21)에 강선(22)(23)을 삽입(결합0시켜 본체(11)의 강도를 보강함으로써 본체(11)를 포함한 전체 강도가 향상되고, 비닐(30)이 안정적이면서 견고하게 압지되고, 결합홈(20)(21)의 바깥 일측에 형성되는 걸림돌부(16a)(17a)에 의해 강선(22)(23)의 분리가 방지되고, 본체(11)의 내외면의 폭 방향으로 형성되는 복수의 보강부(26)(27)(28)에 의해 전체 강도가 더욱 향상되고, 본체(11)
