Releasable two-part buckles

A releasable two-part buckle, comprising:

• a first part having a first strap engaging portion and a pair of stationary hooks;
• and
• a second part having a second strap engaging portion and a pair of arms, each arm having a center axis and a looped end, said pair of arms being resiliently movable between an engaged state having said pair of hooks and arms engaged with one another and a disengaged state having said pair of hooks and arms disengaged from one another,
• wherein said pair of hooks and arms are configured so that, when in said engaged state, a tension applied to said first and second parts induces substantially no bending moment in said pair of arms towards said disengaged state.

A releasable two-part buckle, comprising:

• a first part having a pair of stationary hooks, each hook of said pair of stationary hooks having a leg and a barb, said leg extending along a first of three perpendicular planes, said barb extending inward from said leg along a second of said three perpendicular planes;
• and
• a second part having a pair of arms, each arm of said pair of arms having a first finger, a second finger, and a loop, said first and second fingers extending along said first of said three perpendicular planes and spaced from one another along a third of said three perpendicular planes a sufficient distance to accept said barb between said first and second fingers, said loop extending along said third of said three perpendicular planes and closing an end of said first and second fingers,
• each arm being resiliently movable between an engaged state having said barb engaged with said loop of a corresponding hook and a disengaged state having said barb disengaged from said loop of said corresponding hook.
