An angle-adjustable connector is constructed to include two coupling members connectable to a tool and an air compressor/hydraulic press respectively, a connecting tube connected between the coupling members, the connecting tube having two spherical end portions respectively coupled to the coupling members and secured thereto by steel balls for enabling the coupling members to be turned relative to the connecting tube in different directions to different angles, and a bellows sleeve connected between the coupling members around the connecting tube.
