A tripod lock device for locking a tripod having three identical legs each composed of a fixed leg and a movable leg slidably disposed between a pair of parallel spaced leg members of the fixed leg for adjusting the length of the leg in a telescopic manner. The tripod lock device is composed of three identical leg lock units each associated with one of the three legs of the tripod. Each of the leg lock units includes a frame, an eccentric cam and an engagement portion. The frame has a through-hole in which the leg members of the fixed leg and the movable leg are disposed, with one of the leg members secured to the frame. The engagement portion comprises a rod disposed on the frame at a position adjacent to said one leg member. The eccentric cam includes a presser portion and a hook. When the eccentric cam is rotated in one direction, the presser portion forces the one leg member toward the other leg member to firmly grip the movable leg between the two leg members of the fixed leg, and the hook of one of the leg lock units hooks on the rod of an adjacent one of the leg lock unit. Thus, the three legs of the tripod are locked together against spreading.
