The present invention provides a wire locking structure which is for a boom extension and is capable of reducing the number of wire terminal fittings used and saving a space for a connection part with a boom member. A second connection fitting (44) has a pair of fixing pieces (44a) provided on both sides of an extendable boom (10) in the width direction and fixed to a force boom (14), and wire locking parts (44c) provided between the pair of fixing pieces (44a) such that a locking part (41e) of a force boom extension wire (41) is wound onto a groove (44e) formed along an arcuate outer circumference part. The wire locking parts (44c) on the top and bottom sides of the second connection fitting (44) are arranged in parallel in the direction of the arcuate center axis between the pair of fixing pieces (44a), and the center axis (C1) of the upper wire locking part (44c) is arranged a predetermined distance (S) apart from the center axis (C2) of the lower wire locking part (44c) in the width direction of the extendable boom (10).
