Abstract
A permutation lock includes a housing in which are disposed a plurality of rotary dials and a dial locking spring. The spring includes a base strip and a plurality of spring arms projecting therefrom, there being one spring arm per dial. The base strip is secured in place by means of the forces applied to the spring arms by the dials. Those forces urge the base plate firmly against a floor of the groove by swinging the locking spring about a fulcrum.
