ABSTRACT:
A socket spanner is provided with a retaining device consisting of a socket and an elastic body. The socket has a driven end with a hexagonal hole which is provided in one of six inner side walls thereof with a receiving portion. The elastic body is securely fitted into the driven end such that a retaining side of the elastic body is securely retained in the receiving portion of the hexagonal hole of the driven end so as to prevent the elastic body from slipping out of the driven end, and that a protruded edge of the retaining side of the elastic body is capable of holding securely a nut which is engaged with the driven end of the socket.
