Locking arrangement at telescopically displaceable rods, a first rod (1), which carries one sleeve (6) surrounding a second rod (2), the sleeve being adapted to clamp the second rod by means of an operating part which has the shape of a sliding piece (14) which by means of in pair arranged sliding surfaces (15) co-operate with sliding surfaces on a slide (12, 13) on the sleeve. The sliding surfaces diverge wedge shaped from each other. The slide (12, 13) consists of two parts (12, 13) each carrying one of the said sliding surfaces and being displaceable in relation to each other in a direction which is transverse to the longitudinal direction of the sliding surfaces between a position in which the second rod (2) is locked by clamping the element (6) about it by forcing the parts (12, 13) of the slide into a certain position for the sliding piece (14) and a position in which the second rod (2) is free to be moved in the element in that the sliding piece (14) is in its second position in which a wider part between the wedge shaped diverging sliding surfaces co-operate with the slide. |
