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. |
