Disclosed is a fixing (1) for securing an article (21) to a surface (19). The fixing comprising a coupling arrangement (3) for coupling the fixing to an article such as cabling. Elongate members (5) extend from the coupling arrangement and are moved together to insert the fixing into a cavity (17), and spring apart to retain the fixing in the cavity. The elongate members have resiliently deformable inner formations (9). The inner formations engage with one another and resiliently deform when the elongate members are brought together, thereby increasing the pull resistance of the fixing. The inner formations are inwardly extending branches each presenting a ramped surface oriented towards the distal ends (8) of the respective elongate member, assisting in coupling an article to the fixing.
