ABSTRACT:
An improved releasable gate locking device for preventing the opening thereof by animals. The device is used with a gate and fence structure and comprises a locking pin which includes a head portion having upper and lower walls spaced apart along the pin's axis so as to define a groove therebetween. The lower wall is at right angles to the pin's axis and the upper wall is inclined away from the pin's axis. The pin cooperates with two spaced apart plates having aligned holes for receipt of the pin and the pin will swivel if not raised in a vertical direction. The lower wall prevents the pin from being withdrawn since swiveling of the pin causes the lower wall to engage the lower plate. The upper inclined wall serves to guide the pin back into proper position when a lifting force on the pin is released.
