<p>A strap clamp for e.g. a helmet includes relatively pivotable members (11) which have internal wedge faces (19). Relative pivoting movement of the members (11) releases the wedge faces to permit strap adjustment. In the preferred embodiment the pivotable members are identical, and snap-fitted together. Divergence of the straps on one side gives a degree of self-locking under tension.</p> |
