ABSTRACT:
A slidably adjustable clamp having a locking element in the form of a tapered key for wedging the clamp sliding arm on the clamp rail. The locking element having a bevelled surface on one side is adapted for loose insertion into a rectangular notch formed in the sliding arm opening whereby the locking element can be hammered into wedging engagement between the sliding arm and the rail to lock the arm on the rail. A double-acting wedging effect in both longitudinal and lateral directions is created upon subjecting the locking element to clamping pressures. A second embodiment of the invention comprises a locking element with a planar side which engages a side wall of a trough-shaped recess to laterally engage the sliding arm.
