Abstract: A fastening element, particularly a peg, for fastening bone fragments or the like, is divided into at least two partial elements (10, 12) in the longitudinal direction. The partial elements encompass an expansion element (14). The partial elements and the expansion element being designed and arranged relative to each other such that the expansion element is located between the partial elements. A displacement of the expansion element in the longitudinal direction of the fastening element effecting a displacement of the partial elements in the lateral direction such that the partial elements are forced apart in the lateral direction and the fastening elements are brought from a closed position into an expanded position. The first partial element (10) having a protrusion (110) at the proximal longitudinal end of the inwardly directed sliding surface (42).

Abstract: An actuating apparatus for operating a drive or retardation means of a motor vehicle, comprising a signal converter (26; 60) which produces a control signal dependent on the actuating travel, wherein the signal converter (26; 60) comprises an elastic and conductive shaped body having a first and second outside surface which are arranged at a spacing relative to each other, which is provided with a first electrical contact region (29; 62) which extends over the first outside surface of the shaped body and which is galvanically conductively connected on the one hand to the shaped body and on the other hand to a first feed line (30; 64) and a second electrical contact region (29?; 63) which extends along the second surface of the shaped body and is galvanically conductively connected on the one hand to the shaped body and on the other hand to a second feed line (30?; 65), and wherein the electrical resistance of the shaped body between the two contact regions (29, 29?; 62, 63) is dependent on the spacing of the

Abstract: The invention relates to a fixing element for fixing a first bone fragment (5.1), notably an ankle-bone fragment in ankle joint fractures, to a corresponding second bone fragment (5.2). Said element comprises an elongated spreading part (2) and a fixing part (1) which can be introduced into aligned holes (4, 6) in the bone fragments (5.1, 5.2). The fixing part has a proximal first section (1.1) designed to be introduced into the first bone fragment (5.1) and an adjoining distal second section (1.2) designed to be introduced into the second bone fragment (5.2), as well as a hollow cavity (3) extending substantially along its full length. The fixing part (1) is configured such that it can be fully introduced into the holes (4, 6); by proximal introduction of the spreading part (2) into the hollow cavity (3) at right angles to its longitudinal direction can be spread open by wedge action at least in the area of its two ends so as to be joined to the corresponding bone fragment (5.1, 5.
