A clamp comprises: a first jaw ( 2 ) and a second jaw ( 3 ) having opposing contact surfaces ( 8, 9 ) which are relatively substantially linearly displaceable between a position of minimum separation and a position of maximum separation, wherein in use the opposing contact surfaces ( 8, 9 ) contact the lower surface and upper surface respectively of a structural element, wherein the first jaw ( 2 ) incorporates a first aperture remote from the contact surface and adapted to receive a suspension element or fastener; one or more means for guiding the first jaw ( 2 ) and the second jaw ( 3 ) during relative substantially linear displacement such as to substantially prevent relative non-linear displacement of the opposing contact surfaces ( 8, 9 ); and means for delimiting the substantially linear displacement of the opposing contact surfaces ( 8, 9 ) of the first jaw ( 2 ) and second jaw ( 3 ) to the position of maximum separation.
