The quick-fixing locks the electrical installation device to a profiled collector rail via a one-piece snap-fit latch (2) having projecting side arms (2A) cooperating with retention grooves provided by a holder at the base of the installation device, allowing it to slide in the direction of the collector rail into the locking position and in the opposite direction into a released position. A spring operating lever (2B) has a ratchet cam (2C) engaging a rib of the holder, with spring retaining tongues (2D) cooperating with stop ribs (2F) of the side walls for clamping an edge of the collector rail.
