A clamp assembly is provided for securing an ancillary device (16) to a standing seam (8), the standing seam comprising a protruding web portion (10) with a head portion (12) at an outer extremity. The clamp assembly includes a substantially rigid member (18; 54) adapted to overlie and contact the head portion of the standing seam. First and second substantially rigid arms (22, 24; 58, 60) extend from the member and are adapted to embrace the head portion in co-operation with the member, at least one of the arms (24; 58, 60) being pivotally interconnected with the member at hinge means (28; 62, 64). The first and second arms have first and second free extremities (36, 38; 70, 72) adapted to face one another and to contact opposite sides of the web portion. Threaded fastener means (40, 41; 86) passes through the ancillary device and into a threaded aperture (46; 88) in the member, from an outer surface of the member. The hinge means permits pivoting of at least one of the first and second arms and separation of the first and second free extremities of the first and second arms, for locating the clamp assembly on the standing seam. The threaded fastener means is subsequently tightened to clamp the ancillary device and grip the web portion of the standing seam in jaw-like manner by the first and second free extremities of the first and second arms.
