ABSTRACT:
A sliding block for adjustably mounting e.g. an ear cup at a protective helmet or a head clamp having a U-shaped carrier includes a base member and a channel-shaped cover. The base member includes a prismatic head and a shaft projecting therefrom, and a passage extends through the head and the shaft. Grooves are provided at two mutually opposite sides at the head for receiving the shanks of the carrier. In mounted position the cover will enclose the head and lock the shanks in the grooves, however permitting a sliding movement of the block along the carrier.
The cover has an internal projection snapping into the mouth of the passage at the head, and the opposite mouth of the passage is provided with tongues for engaging a stud on the ear cup.
