Abstract: A retractable door or window stop member includes a barrel which defines a recess in a top surface. A spigot is pivotable about a first axis extending transversely of the recess. An adjustment means enables the spigot to be pivoted between its first and second positions. A spring means is in the recess and acts between the spigot and the barrel to urge the spigot to and thereby tending to positively retain the spigot in its first position. The spring means is secured in relation to the barrel between the first axis and the second axis at each of the opposite sides of the recess, the spring means having an intermediate position which extends towards the first axis and which engages a protrusion on the underside of the spigot to thereby urge the spigot to its first position.
