A prosthetic lower leg or prosthesis comprising two plates mutually connected downwardly and to a prosthetic foot, while upwards they are enlarged into circular coacting sleeve halves, together forming an adjustable carrying sleeve. By means of an annular tensioning device the sleeve can be tightened round the leg stump which can be fixed laterally in the prosthesis by special tension straps between the plates, as well as longitudinally relative to the prosthesis by means of a strap which is attached to the carrying sleeve and tightenably laid round the leg stump in a loop. The weight on the leg stump is substantially transferred to the prosthesis via bands attached to the outside of a stocking on the stump and extend up over the edge of the carrying sleeve and from there down on the outside of the sleeve where the free ends of the bands are anchored.

A prosthesis for replacing an amputated lower leg comprising a front plate and a back plate opposing the front plate, said plates having lower portions and upper portions and being rigidly joined to each other at their lower portions and adapted to be articulately connected at their lower portions to a prosthetic foot, the upper portion of each plate being shaped as a sleeve half and cooperating with the other sleeve half in a circular configuration to form an upward bowl-like enlarged carrying sleeve, the material of the plates being sufficiently spring-like to allow the upper portions of the plates to be resiliently pulled apart so that a leg stump can be inserted into the carrying sleeve; means for pulling the sleeve halves together so as to maintain a firm grip around a leg stump, means for laterally adjusting the prosthesis relative to a stump, and means for fixing the prosthesis longitudinally relative to a stump.
