An adjustable vehicle seat belt anchor comprises an elongated rail member and a slide member slidably received by the rail member. The rail and slide members are of complementary cross sections, one being generally C-shaped with inturned and offset flanges along each side and the other being generally channel-shaped with out-turned and offset flanges along each edge. A spring-biased retaining pin is movable orthogonally to the direction of movement of the slide member into a selected hole in the rail member. A flange on the end of the pin forms a shoulder that can engage the back edge of the hole to prevent dislodgment of the pin under a high downward force. A deformable member positioned between the hole wall and the pin normally keeps the pin shoulder from engaging the hole edge but is deformed under a high force to permit such engagement.
