Ceiling suspension system for a suspended ceiling, comprising: - a primary profile which, in an installed state, extends in a first direction (x); - one or more suspension elements for the suspension of the primary profile; - a secondary profile which, in an installed state, extends in a second direction (y) perpendicular to the first direction (x), below the primary profile and which is configured to support ceiling plates; and - a coupling bracket for coupling the primary profile with the secondary profile, wherein the coupling bracket comprises: • a main body that defines a space through which, in the installed state, the primary profile extends; • two coupling legs which extend from the main body on both sides of the space while, in the installed state, lying at a first side of the secondary profile and coupling with the secondary profile; and • two retaining tabs which extend from the main body on both sides of the space while, in a retaining position in the installed state, lying at a second side situated opposite the first side of the secondary profile and enclosing the secondary profile form-fitting together with the primary profile and the coupling legs, characterised in that, the coupling bracket both in a non-installed state as well as in said installed state, has its retaining tabs lie in the retaining position, wherein at least the retaining tabs of the coupling bracket are made resilient elastically deformable for being movable out of their retaining position towards a passing position in which the secondary profile is movable into or out of its form-fitting enclosing during coupling of the secondary profile with the coupling legs, and for the resilient elastically deformable retaining tabs to then spring back towards their retaining position. - a primary profile which, in an installed state, extends in a first direction (x); - one or more suspension elements for the suspension of the primary profile; - a secondary profile which, in an installed state, extends in a second direction (y) perpendicular to the first direction (x), below the primary profile and which is configured to support ceiling plates; and - a coupling bracket for coupling the primary profile with the secondary profile, wherein the coupling bracket comprises: • a main body that defines a space through which, in the installed state, the primary profile extends; • two coupling legs which extend from the main body on both sides of the space while, in the installed state, lying at a first side of the secondary profile and coupling with the secondary profile; and • two retaining tabs which extend from the main body on both sides of the space while, in a retaining position in the installed state, lying at a second side situated opposite the first side of the secondary profile and enclosing the secondary profile form-fitting together with the primary profile and the coupling legs, • a main body that defines a space through which, in the installed state, the primary profile extends; • two coupling legs which extend from the main body on both sides of the space while, in the installed state, lying at a first side of the secondary profile and coupling with the secondary profile; and • two retaining tabs which extend from the main body on both sides of the space while, in a retaining position in the installed state, lying at a second side situated opposite the first side of the secondary profile and enclosing the secondary profile form-fitting together with the primary profile and the coupling legs, the coupling bracket both in a non-installed state as well as in said installed state, has its retaining tabs lie in the retaining position, wherein at least the retaining tabs of the coupling bracket are made resilient elastically deformable for being movable out of their retaining position towards a passing position in which the secondary profile is movable into or out of its form-fitting enclosing during coupling of the secondary profile with the coupling legs, and for the resilient elastically deformable retaining tabs to then spring back towards their retaining position.
