A spacer for use in forming a wall of glass blocks which includes a pair of parallel elongated first arms, a pair of parallel elongated second arms, with each of the second arms being perpendicular to a corresponding one of the first arms so as to form a pair of spaced apart crossed arms. An elongated connecting bar interconnects to the crossed arms a plate positioned parallel to each of said crossed arms. A frangible coupling affixes each of the plates to a corresponding one of the crossed arms and an elongated vane element extends out from and across the plates and passes through a notional line through a center of each of the frangible couplings so that a user may grip and twist the vane element so as to impart a torque about the notional line which shears an associated frangible coupling at its joint with an associated one of the crossed arms without imparting any translational force to the spacer.

L'invention porte sur une entretoise utilisée pour construire un mur de briques de verre, qui comprend une paire de premiers bras parallèles allongés, une paire de deuxième bras parallèles allongés, où chacun des deuxièmes bras est perpendiculaire au bras correspondant de la paire des premiers bras de manière à former une paire de bras en croix espacés l'un de l'autre. Une barre de raccordement allongée relie aux bras en croix une plaque montée en parallèle auxdits bras. Une monture frangible rattache chacune des plaques à un des bras en croix correspondant et un élément à ailettes allongé se prolonge à partir des plaques et au travers de celles-ci pour traverser une ligne théorique à travers un centre de chacune des montures frangibles. Ainsi, un utilisateur peut saisir et tordre l'élément à ailettes afin d'imprimer une torsion autour de la ligne théorique qui va cisailler une monture frangible à son articulation avec un des bras en croix associés, sans appliquer de force de translation à l'entretoise.
