ABSTRACT:
A slide fastener and apparatus is provided for securing a fixture having a hole therethrough to a surface having a hole therethrough. The apparatus comprises a brace that operates in two positions: a retracted position for insertion through the aligned holes, and a locking position that is substantially perpendicular to the central axis of the aligned holes. A tail is flexibly connected to the mid-section of the brace and adapted to slidably carry a lock piece that urges the brace to the locking position and bears upon the fixture to secure the fixture to the surface. The lock piece may be advanced inward toward the brace, but not retracted outward away from the brace.
