Quick fit coupling for scaffolding truss used in e.g. lighting installations, has locking device extending through three bores in tubular part, coupling part and insert

摘要

The tubular part (5) contains a third bore whose central axis is aligned with the central axes of the first and second bores (6, 7) when the coupling is assembled. The locking device (8) for holding the coupling together extends through the third bore. The coupling comprises an insert(4) which is held by a tubular part and used to hold a coupling part connected to the truss (2). The insert contains a first bore and the coupling part contains a second bore. The locking device extends through the first and second bores when the coupling is assembled.
