The present invention discloses a splice holder, which is used for holding at least one splicing sleeve (4), each of the splicing sleeves (4) is used for coupling two optical fibers. The splice holder comprises: a body; a splice channel (7) provided on the body; and an elastic device (9) in each splice channel, wherein the elastic device holds the splicing sleeve (4) elastically in the splice channel. The present invention also includes a communication socket having a splice holder mounted therein. By the splice holder of present invention, optical fiber connection points can be accommodated in a communication socket, so that electrical cables and optical fibers in the communication socket may be managed in an orderly way. Furthermore, inclusion of the inventive splice holder ensures than a minimum bending radius of optical fiber can be maintained when the optical fiber is stored in the communication socket.
