Abstract: A prosthesis includes first and second prosthetic limb components and a fastening system for fastening the first and second prosthetic limb components. The first prosthetic limb component is provided with a first coupling member and the second prosthetic limb component is provided with a second coupling member. The first coupling member includes a cylindric member having an axis, with a wall generally parallel with said axis. The second coupling member includes a circular skirt element having an axis and having corresponding external dimensions to the cylindric member whereby to permit a sliding fit therewith in an unfastened state. The fastening system includes a resilient member having an axis and is operable to expand laterally, orthogonally with respect to the axis such that, in a coupling mode of operation, the lateral expansion operates to cause the skirt to be in a state of frictional engagement with the other coupling member.
