Abstract

A scaffolding system comprises a diagonal brace 6 with a transverse pin 13 for engaging an eye 8 of a ledger end fitting. To hold the pin in the eye, the pin has an internal snap-action latch 15, with a hooked projection end to engage a complementary configuration 21 on the eye. The latch is provided with an operating arm 18 projecting from the pin, for moving the latch to a position retracted within the pin to enable the pin to be removed from the eye. <IMAGE>
