A solar collector comprises an evacuated radiation transparent enclosure (8), an absorbing section (9) comprising a radiation absorbing means (10), an elongate tube (11, 15) for a working fluid in contact with the radiation absorbing means (10) and a retaining means (25) for retaining the absorbing means (10) in position in the solar absorbing tube (8). The retaining means (25) comprises a single piece wire clip having a clamping portion (26) for clamping onto the outer surface of the working fluid tube (11, 15) and a pair of resilient side support sections (27) flanking the clamping portion (26). The side support sections (27) extend so that portions thereof engage against the inner surface of the solar absorbing tube (8). |
