Abstract
A latch device is provided with a stationary cylinder to be fixed on a structure on which a door is hinged and a rod adapted to be driven into the cylinder against the resilience of a spring by a strike on the rear side of the door during the closing of the door, and the rod has the front half thereof formed in the shape of a pair of retention pieces connected separately through hinges of a small wall thickness into the rear half of the rod, so that while the rod is pushed into the stationary cylinder, the inner wall surface of the stationary cylinder will enable the retention pieces to grasp the strike and, while the door is opened, the rod will protrude from the stationary cylinder and slightly push the door open and, at the same time, the retention pieces will release the strike from retention therein.
