is disengaged from female member 144 when side tangs 142 are pinched together and center arm 143 is freed from catch extension 148 center arm 143 is deflected away from catch extension 148 to be free of catch extension 148 to permit male member 145 to be disengaged a button 147 acts as an actuator to deflect center arm 143 away from catch extension 148 button 147 includes an actuating area 151 that contacts center arm 143 and displaces it away from catch extension 148 in an exemplary embodiment a gap 152 is provided between actuating area 151 and center arm 143 so that button 147 moves through a non operative range before actuating area 151 begins to influence center arm 143 gap 152 accordingly provides a non operative range for the actuation of button 147 to promote a child resistant feature where button 147 appears non operative when a child attempts to actuate button 147 female member 144 includes a top wall 154 and a bottom wall 156 that contribute to support for the structural integrity of female member 144 in addition male member 145 includes a tapered area near opening 149 to contribute to the operability of buckle 140 when center arm 143 is displaced away from catch extension 148 tapered area 141 contributes to easing the release of center arm 143 from catch extension 148 by providing additional clearance so that the latching mechanism operates with less deflection and without the application of an overly burdensome force center arm 143 can generally remain at a thicker dimension than tapered area 141 so that.
