A connecting device for securely connecting cables comprises a first cable, a male coupling, a male terminal assembly, a second cable, a female coupling, and a female terminal assembly. The first and second cables are threadedly secured to the male and female couplings respectively. The female coupling comprises a forward recess and a sealing ring therein. Once the male and female couplings are coupled, a sealing structure is formed as a projection of the male coupling is urged against the ring and the recess. The device is simple in structure, waterproof, and reliable.
