The assembly includes a handrail support component and a connector component. The connector component is attachable to the support component and an attachment formation. The support and connector components can be tightened to each other to tighten the connector component to the attachment formation for tightening the support component onto the slab. The invention extends to a handrail system including the slab, and to a method of installing handrail components on the slab. ## Claims ### Claim 1 A handrail support assembly adapted for attachment to a construction element, the element including a pre-cast concrete wall slab in the form of a rectangular cuboid having a front face and an opposite rear face, and having a vertical operational orientation in which said front and rear faces extend upwardly, the slab further having, when in the operational orientation, an upper edge and an opposite lower edge, and two opposite side edges, each of the upper, lower and side edges extending between the front face and rear face, the construction element further including a securing element having a connection portion exposed relative to the slab and an anchor portion pre-cast with, and embedded in, the slab and formed so as to engage the slab whereby the securing element is adapted for lifting of the construction element by a lifting apparatus when the lifting apparatus is attached to the connection portion, the support assembly comprising: a handrail support having first engagement means; and a securing element connector having a first portion adapted for interlocking detachable connection to the connection portion and a second portion having second engagement means and being adapted for attachment to the handrail support, wherein the handrail support and second portion are adapted to be tightened to each other by inter-engagement of the first engagement means and second engagement means, such that the handrail support is tightened into fixed engagement with the slab, wherein the handrail support assembly has at least one outer surface which is adapted to conceal the first engagement means and second engagement means when the handrail support and second portion are tightened to each other. ### Claim 2 (depends on 1) The handrail support assembly according to claim 1, adapted for attachment to the construction element wherein the front face extends in a first plane and the rear face extends in a second plane parallel to, and spaced from, the first plane, wherein the securing element is located between the first and second planes. ### Claim 3 (depends on 1) The handrail support assembly according to claim 1, adapted for attachment to the construction element, wherein the slab defines a recess, the securing element being disposed within the recess. ### Claim 4 (depends on 1) The handrail support assembly according to claim 1, adapted for attachment to the construction element, wherein the connection portion of the securing element and the first portion of the securing element connector are adapted for hooking engagement with each other. ### Claim 5 (depends on 1) The handrail support assembly according to claim 1, adapted for attachment to the construction element, wherein the connection portion of the securing element is in the form of a lug. ### Claim 6 (depends on 5) The handrail support assembly according to claim 5, adapted for attachment to the construction element, wherein the connection portion includes a stem portion and a shoulder portion which is broader than the stem portion, and the first portion of the securing element connector includes a slot for receiving the stem portion therealong such that the first portion is adapted to be retained by the shoulder portion. ### Claim 7 (depends on 6) The handrail support assembly according to claim 6, adapted for attachment to the construction element, wherein the slot extends along a curved path such that the securing element connector is attachable to the securing element by rotation of the securing element connector relative to the slab. ### Claim 8 (depends on 1) The handrail support assembly according to claim 1, adapted for attachment to the construction element, wherein the second portion of the securing element connector includes a threaded rod and the handrail support includes a complementary threaded cavity adapted to receive the rod, wherein the securing element connector and handrail support are configured to be attached to each other by said threaded portions. ### Claim 9 (depends on 8) The handrail support assembly according to claim 8, adapted for attachment to the construction element, and for the securing element connector to be tightened in relation to the securing element on relative rotation of the threaded rod and threaded cavity. ### Claim 10 (depends on 1) The handrail support assembly according to claim 1, adapted for attachment to the construction element, wherein the handrail support includes at least one laterally extending brace configured to engage with the upper surface of the slab when the handrail support is tightened into fixed engagement with the slab. ### Claim 11 (depends on 10) The handrail support assembly according to claim 10 wherein the brace is in the form of a plate formation. ### Claim 12 A handrail system, comprising a construction element and a handrail support assembly, wherein: the construction element includes a pre-cast wall slab in the form of a rectangular cuboid having a front face and an opposite rear face, and having a vertical operational orientation in which said front and rear faces extend upwardly, the slab further having, when in the operational orientation, an upper edge and an opposite lower edge, and two opposite side edges, each of the upper, lower and side edges extending between the front face and rear face, the construction element further including a securing element having a connection portion exposed relative to the slab and an anchor portion pre-cast with, and embedded in, the slab and formed so as to engage the slab whereby the securing element is adapted for lifting of the construction element by a lifting apparatus when the lifting apparatus is attached to the connection portion;
