A fastener for fastening a carpet, mat or other floor covering to a supporting surface, comprises a pair of fastener parts 2, 20 each having planar base 4, 30 which is securable to the covering 42 and/or the supporting surface 46. An array 15, 23 of fastener elements of substantially constant horizontal cross section is provided on the base 4, 30 and extending perpendicular thereto, the elements 14 of one fastener part 2 intercalating with the elements 22 of the other part 20 when the fastener parts are joined with their bases substantially parallel to one another. The minimum surface to surface spacing between adjacent elements of one part is less than the diameter of an element of the other part whereby the parts cannot be separated by movement in the plane of the base but there is substantially no resistance to separation by movement in the direction perpendicular to the base 4, 30.
