Abstract
A coupling device for engagement with an anchor member is provided. The coupling device includes a lever that moves between a closed position that substantially covers the mouth of the device and an open position in which the mouth is substantially uncovered by the lever. The lever may be moved to the open position by camming forces or by direct manipulation of a portion of the lever by a user. The coupling device may include a cover with a recognizable shape such as a pet or fictional character. The protruding ears and/or head of the recognizable shape aid in the gripping and operation of the device and the mouth receives the anchor member.
