Claims7
A socket spanner with a retaining device comprising a socket and an elastic body;
- wherein said socket has a driven end with a hexagonal hole which is provided in an inner wall thereof with two axially extending retaining grooves in substantially diagonally opposing positions relative to each other;
- said elastic body comprising a press portion and at least one longitudinally extending retaining leg which extends from said press portion;
- said press portion having a full-ring configuration with a diameter slightly greater than a distance between two opposing faces of said hexagonal hole so as to allow said elastic body to be received and retained in said hexagonal hole;
- said retaining leg comprising a bent portion, a first straight portion, a second straight portion, and a radially inwardly protruding portion, all of said portions being receivable in said retaining groove, said bent portion connecting said retaining leg with said press portion, said first and second portions being generally parallel to an inside surface of said retaining groove, and said radially inwardly protruding portion being disposed between said first and second straight portions which is constructed to be pressed into said groove and exert an urging against a nut when the nut is inserted into said hexagonal hole.
