A panel unit (2) for constructional purposes has at least two joining flanges (10, 12) on opposite surfaces (4, 4) located at, or adjacent to, a common edge of the panel unit, and projecting in mutually opposite directions. Two such panel units (2) may be juxtaposed end to end and secured by a two-part connector (17) having a base portion (18) that is adapted for attaching to a fixed structural element (20) and for anchoring to the flanges (12) on a first surface (4) of the panel units 2, and a cap (19) adapted for anchoring to the flanges (10) on an opposite surface (4) of the panel units (2) and for anchoring to the base portion.
