A webbing length adjustor adapted to clamp webbing when tension is applied to a tension end of the webbing. The adjustor has a webbing guide, a clamp element pivotally mounted on the webbing guide, a locking cam on the clamp element which in a locked position clamps the webbing between the locking cam and the webbing guide to prevent movement of the webbing through the adjustor when tension is applied, a release actuator, and a projection on the clamp element that abuts against the webbing between the locking cam and the tension end thereof so that the webbing exerts a force against the projection which urges the clamp element in a direction that holds or moves the locking cam in or into a locked position. The projection is adapted to always slightly deflect the webbing, even when the clamp element is in its locked position.
