DEFINITION

Classification: 24/644

Blocking removal of formation on projection from complementary formation on side wall of cavity:

(under subclass 643) Receiving member wherein the swinging component moves into or out of a position which prevents the separation of a distinct interlocking formation (e.g., aperture) located on the projection member from a distinct stationary interlocking formation located on the axially extending walls of the cavity having a shape complementary to the formation of the projection.

(1) Note. The formation within the cavity must be more than a simple extension of and be spaced from the initial structure defining the access opening.
