DEFINITION

Classification: 24/559

Interlocking faces:

(under subclass 545) Engaging surfaces having a projecting portion of one engaging surface (e.g., button, hook) inserted within a cavity portion of the opposed gripping surface (e.g., open loop, slot member) which receives both it and the structure-to-be-secured* in such a manner as to subsequently restrict their relative movement in the direction force is transmitted thereto by the structure-to-be-secured*.

(1) Note. The mere intermeshing or mating of opposed engaging surfaces is not considered to be interlocking unless the intermeshing or mating portions tightly interfit or are otherwise held together to restrict the separation of the engaging surfaces.
