Partitions

A partition apparatus for attachment to a supporting structure (1) to partition a space, comprising a panel part (3) for providing the partition and an interface part (4) for attachment to the supporting structure to form an interface joining the panel part to the supporting structure. One of the panel part and the interface part comprises a groove (12) and the other of the panel part and the interface part comprises a tongue (4) dimensioned for insertion into the groove in a direction transverse to the longitudinal axis of the groove. When the tongue is inserted into the groove, the tongue and the groove are pivotable relative to each other through an angle exceeding 10 degrees thereby to form a tongue-and-groove joint pivotingly joining the panel part to the supporting structure.
