A locking pin for retaining a body on a drilled shaft or stud has a first straight section the end of which passes through the aperture in the stud. Opposite the aforesaid end the straight section terminates in a long sweeping 270 DEG section that straightens out into a leg of a U-shaped section having two legs lying astride the stud and lying at right angles to the straight section. The legs of the U-shaped member pass over the straight section and are angled down to contact the surface of the body to be retained on the stud whereby to provide a locking pin only two diameters of the wire high, having three lines of contact with the surface to prevent wobble and to prevent a line or rope from getting under the pin and lifting it off the stud. The pin is readily removed by placing a thumb nail under the base of the "u" or an opposed loop and lifting until the legs of the U are raised above the end of the stud.
