A fastener ( 10 ) for fastening together elongate objects ( 26 ), such as scaffolding and other items used in the construction industry, is described. The fastener includes first and second portions ( 12, 14 ) which engage with one another by means of male ( 16 ) and female ( 18 ) members. The first and second portions are relatively rotatable, and may be aligned in a range of positions prior to fastening the device. The male and female members serve to retain the fastener in the closed position, and may use a ratchet arrangement, or may use a friction fastening. Also described is a tool ( 30 ) for securing the fastener. |
