An infinitely positionable mechanical lock having a housing and at least one bushing fixed to the housing, the bushing having an inclined spring abutment surface. A rod is axially slidable through the bushing relative to the housing. A coil spring is wound about the rod, the spring having a normal inner diameter smaller than the diameter of the rod such that the coil spring grips the rod against translational motion within the housing. The spring is prebiased against the inclined surface of the bushing into normal locking engagement with the rod absent an axial load on the rod relative to the housing. A release assembly is actuatable for partly unwinding the coil spring to thereby release the rod for movement relative to the housing.
