Abstract
A locking device is made of a casing having a substantially trapezoidal shape and a rod extending through the casing. The rod has a central portion and two side guides to permit the central portion to come into locking engagement with a toothed roller placed inside toothed triangular recesses of a V-shaped member. The V-shaped member has a top portion provided with a fork. One side of the V-shaped member is connected to an inner edge of the casing and the other side has a cutout with a lower rounded portion and an upper straight portion provided with a slope. The cutout cooperates with a cam comprising a flat portion and a finger.
