A prosthetic lock assembly of the ratchet type for connecting a liner for a prosthetic socket to a prosthesis. The lock assembly includes a two part locking mechanism held together by suitable fasteners. Removal or loosening of the fasteners enables a user to separate the two parts from one another in the event a sock gets into and jams the locking mechanism. In a first set of four embodiments, a latch is formed in a first part of the locking mechanism and in a second set of four embodiments, the latch is formed in a second part of the locking mechanism. The lock assembly may be mounted internally or externally of the prosthetic socket. The first part of the locking mechanism may be a laminating ring or a thermoforming plate and the second part may be a mounting block with or without a pyramid for controlling a prosthetic pylon.
