There is provided an outrigger connection locking device used in a crane apparatus (3) including a boom (6), a swivel base (5) that supports the boom (6) so as to be raised and lowered, a carrier frame (4) on which the swivel base (5) is mounted, and an outrigger (7) removably mounted to the carrier frame (4). The outrigger locking device includes: a connection pin (84, 85) that can be inserted into a carrier frame hole (44) formed in the carrier frame (4) and into an outrigger hole (73) formed in the outrigger (7); a telescopic cylinder (81) that performs a telescopic motion that allows the connection pin (84, 85) to move to a location in which the connection pin (84, 85) is inserted into the carrier frame hole (44) and the outrigger hole (73); a connection locking unit (9) that restricts the connection pin (84, 85) inserted into the carrier frame hole (44) and the outrigger hole (73) from moving; and a remote operation mechanism (10) for connection locking that can operate the connection locking unit (9).
