Abstract: A connector for connecting panels surrounding an enclosure for cattle or horses allows one person working alone to connect adjacent panels. The connector comprises a U-shaped portion having a down-turned leg on one end and an up-turned leg on another end. The down-turned leg is pivotally connected to a post of a first panel. A post of a second panel is moved adjacent the post of the first panel. The U-shaped portion is then pivoted around the post of the second panel. A slidable sleeve, which is slidably engaged to the first post, is lowered to slidably engage the up-turned leg of the U-shaped portion, thereby connecting the adjacent panels.
