A coupling element for connecting a channel of a first strut with a groove of a second strut comprises two arms (2, 4) hinged together at one end and having outwardly facing hooks (16, 18) at a second end. An adjuster screw (28) clamps the hooks (16, 18) apart and a spring arrangement (20) biases the hooks (16, 18) apart. The spring arrangement (20) is located between the adjuster screw (28) and the hooks (16, 18). |
