A respective cap (3, 4) is arranged on an inner (1) and an outer (2) tubular part of the guide handle. The first cap (3) bears on the inner surface (5) of the inner tubular part (1) and extends outwards over the end surface (6). In contrast, the second cap (4) bears against the outer surface (7) of the outer tubular part (2) and extends inwards over the end surface (8). Arranged in the first cap (3) is an actuating lug (9) which cooperates with rams (10, 11). Said rams extend through openings (12, 12', 13, 13'), in the first cap (3) and in the inner tubular part (1). The longitudinal adjustment of the guide handle can thus take place in the simplest manner possible by way of the release button (9) using the hand holding the handle, an unintentional, relative displacement of the tubular parts being excluded. <IMAGE> |
