Abstract: Disclosed herein is a panel connection assembly (10) for connecting adjoining prefabricated building panels (200,400). The panel connection assembly (10) comprises an elongate first component (20) adapted for connection to a surface of a first panel (200) and an elongate second component 40 adapted for connection to a surface of a second panel (400), such that when the first and second panels (200,400) are joined in use, the first and second components 20, 40 are sandwiched between the panels. A first locking member (60) is removably engageable with the first and second components (20,40) for restraining the first and second components against shearing movement orthogonal to their longitudinal axes (22,42). A second locking member (80) is removably engageable with the first and second components 20, 40 for restraining the first and second components against movement away from one another orthogonal to their longitudinal axes (22, 42).
