ABSTRACT:
A prosthetic attachment locking device includes a body and a releasing mechanism. The body has an axial hole that extends from a first surface to an opposing second surface, and a pawl receiving recess that communicates with the axial hole. The releasing mechanism has a central axle with a pawl that is received in the pawl receiving recess. The central axle has a clutch bearing that rotates the pawl in a first direction when an attachment pin is inserted into the axial hole. The clutch bearing secures the attachment pin in the body and is reversible such that an attachment pin can be inserted from the first surface or the second surface of the body. Because the prosthetic attachment locking device is reversible, the releasing mechanism can be positioned to project toward an interior of a residual limb whether used on a right-side residual limb or a left-side residual limb.
