Conduit ground ?

Is there a problem with extending ground by connecting to metal conduit (that is grounded via the breaker box) using a conduit ground clamp and wire to a receptacle?

The metal box would be grounded by the conduit. You don't need to connect a wire from the conduit to the receptacle, but from the metal box to the receptacle by using a ground screw installed in the metal box or a ground clip attached to the side of the metal box.

To clarify: I failed to pull a gnd wire when I extended my shop circuit ( metal conduit) to a shed.
Therefore I pulled a green wire to the shed & attached it to the receptacle ground.
I connected this gnd wire to the shop conduit & tested the receptacles in the shed with a known working 3 led tester.
The result NO ground.
I'm baffled, I have checked continuity at each conduit connection where gnd could be lost, but they all ohm out ok.

When you say you ran metal conduit to your shed, I hope you ran Rigid conduit if it is buried in the ground. EMT is not listed for direct burial.
