Abstract: Improved apparatus is provided for temporarily securing together scaffolding members. A slotted stud fixed to a scaffolding support member is provided with a pivotal dog rotatable within the slot for receiving the hole punched end of a cross member. A spring and washer having a transverse bar member within the slot are permanently retained on the stud to prevent misuse of the device. Rotation of the dog to receive the cross member causes axial movement to the washer and compression of the spring. Further compression of the spring by the cross member allows the dog to return to its lock position by gravity. The spring, washer, and dog thus cooperate to either expel the cross member from the device or lock the cross member in place, which substantially increases scaffolding safety.
