Abstract: An attachment apparatus designed to facilitate the quick connection and release of movable objects relative to a fixed surface. The apparatus provides a fixed base shoe member which is firmly secured to a stationary surface. The shoe member is constructed from a spherical segment having a channeled groove extending therethrough, inwardly extending flanges are provided in conjunction with the channel groove for holding a movable foot member within the groove. The foot member is secured to a coupling apparatus which carries a retainer means for locking the foot member in place directly beneath the inwardly extending flanges of the shoe member.
