The locking tensioner comprises first and second elongate arms connected by a bridge. The distal end of the second arm has a tongue. The distal end of the first arm has a head with an aperture dimensioned to receive a chain therethrough, the head further having a slot dimensioned to releasably receive the tongue within the aperture. The second arm is pivotable relative to the first arm between a locked and an unlocked configuration. In the unlocked configuration, the tongue is disposed in the aperture to permit the chain to move through the aperture. In the locked configuration, the tongue applies a shear force between the chain and the head to restrict the movement of the chain. The bridge biases the first and second arms towards the locked configuration.
