Abstract: A prosthetic connector assembly (10) for adjustably connecting a socket (22) with a prosthetic limb includes an end plate (12) having a top side (16), a bottom side (18), and a central opening (14) therein. A socket (22) extends upwardly from the top side (16) of the end plate (12) and an attachment member (66) is supported on the bottom side (18) thereof. An oblong washer (26) is disposed within the socket (22) and is supported by the top side (16) of the end plate (12). A bolt (84) extends through the attachment member (66), washer (26), and central opening (14) in the end plate (12) to retain the washer (26) and attachment member (66) against the end plate (12) while permitting relative adjustment of the attachment member (66) with respect to the end plate (12).
