ABSTRACT:
A street name sign of a vandalproof type which comprises one or more sign heads of a hollow aluminum-frame construction and a center staff passing centrally through the sign heads and down into the post supporting the sign, is provided with a lock collar clamped to the lower end of the center staff and itself having a one-way locking action against the inside wall of the post permitting the sign to be readily pressed down onto the post but locking the sign against any unauthorized removal. The lock collar is secured firmly to the center staff preferably by clamping pressure exerted through the sign assembly to hold the whole assembly on the center staff in an integral construction.
