PROBLEM TO BE SOLVED: To provide a connector sealing curable composition which gives, on curing, a cured product excellent in the adhesion to a metal, hard to thermally expand and thermally shrink, and furthermore hard to swell against a high temperature engine oil. SOLUTION: The curable composition for a sealing connector comprises a polyol component comprising a polyesterpolyol composed of ricinoleic acid and a polyhydric alcohol, a diol, and a trifunctional polyetherpolyol and a polyisocyanate component, and the hardness D of a cured product after curing the curable composition when measured according to JIS K 6253 is 60-90.
