A locking device in a telescopic tripod leg assembly comprising at least two leg elements, for releasably fixing one of two inner and outer leg elements relative to the other in an extended position of the tripod leg assembly. An outer leg element and a frame secured thereto are provided in their walls with an aligned through-opening, and a locking lever having a cam portion at its end is pivotally connected to the frame so that the cam portion is positioned within the aligned through-opening. A pressure piece is placed on the wall of the inner leg element within the through-opening and a spring piece is supported on projections at both sides of the pressure piece. When the locking lever is pivotally moved downward, the spring piece is pressed by the cam portion thereof and curved into a groove between the projections, whereby the inner leg element can be positively fixed relative to the outer leg element by the elasticity of the spring piece. |
