A bracket for attachment to a railing spindle includes an elongate socket body composed of resilient, elastomeric material and having a forward sidewall, lateral opposed sidewalls, and rearward sidewall portions defining an elongate chamber therebetween. An elongate access channel is defined between the rearward sidewall portions having a width nominally less than the width of a railing spindle. Outward biasing force is exerted upon the lateral sidewalls of the socket body and acts to widen the access channel and allow passage of the railing spindle in the socket body chamber. Release of the biasing force allows the lateral sidewalls and the rearward sidewalls to resume an original relationship and narrow the access channel. A method of effecting a mounting of the bracket to a railing spindle includes the steps of: positioning the socket body of the bracket at an acute angle adjacent the railing spindle with a lower end of the socket body close to the railing spindle; registering the railing spindle into the open lower portion of the socket body chamber; rotating an upper end of the socket body about the lower end toward the railing spindle; applying a directional biasing force to the lateral sidewalls that moves the rearward sidewall portions outward and widens the access channel therebetween; passing the railing spindle through the widened access channel and into the socket body chamber; and removing the applied biasing force, releasing the lateral and rearward sidewall portions to resume an original position and narrow the access channel.
