Referring to Fig. 4 it will to users, and in the instance of children to posi be seen that the nose 12 of the" latch is bevelled tively prevent the pin from being swallowed in as indicated at H and has a notch l8 on its lower open position thereof. side to receive the tongue 4 thereby to positively:

In order to assemble 10 automatic means for additionally latching the the latch within the keeper an opening I9 is propin in closed position, which means is normally in Vided at one end of the keeper into which the operative position and upon engagement with latch is slid, following which the finger piece the pin is moved to allow the pin to occupy closed is applied and secured by its pin l6 and then 15 position, and then returned to normal position so the opening I 9 may be closed by solder or other 5 as to positively latch the pin in its closed posimeans.
