An
assembly includes a bar having a sleeve
assembly connected to an end portion. The end portion has a first outer
diameter, a shoulder section having a smaller
diameter than the first outer
diameter, a neck section having a smaller outer diameter than the shoulder section, and a head section having a larger outer diameter than the neck section, such that the neck section forms a recessed slot. The sleeve
assembly includes a sleeve having a connection assembly for connecting the sleeve to the end portion, which includes a
split ring having semi-annular pieces received within the recessed slot and around the neck section, a proximal
washer positioned axially inward from the
split ring, around the shoulder section, a distal
washer positioned axially outward from the
split ring, around the head section, and an annular member extending circumferentially around the split ring to retain the semi-annular pieces within the slot.
