Abstract: An apparatus for securing and releasing a stake in a stake pocket comprises a spring having a fastening end and a latch end. The fastening end is attached to an inside surface of the stake and the spring is biased such that the latch end positively engages the stake pocket. A selectively actuable release that effects the disengagement of the latch end of the spring from the pocket is also included. The release is disposed such that it may be actuated by a user's foot, when the user is standing at the level of the stake pocket in an upright position.
