A connection assembly comprising a first connector and a second connector for a communication cable (120, 220); the first connector and the second connector being configured to engage with one another so as to reach a mounted position in which all degrees of freedom of movement of the first connector relative to the second connector are blocked, except translations in an assembly direction (X-) and a disassembly direction (X+); the connection assembly further comprising at least one tab; the connection assembly being arranged in such a way that for each tab among said at least one tab: when the tab is secured to the first connector and the first and second connector are in the mounted position, the tab is returned to a mounted position in which a retaining portion of the tab is disposed facing a retaining surface of the second connector associated with the tab in a disassembly direction (X+); the disassembly direction being a direction in which the retaining surface moves relative to the first connector upon disconnection of the second connector from the first connector; and as a result, in the mounted position, the tab prevents the second connector from disengaging from the first connector; characterized in that the connection assembly further comprises at least one securing part capable of being placed in a mounted position in which, when said at least one tab, the first and the second connector are in the mounted position, said at least one securing part prevents at least one secured tab from being biased or from deforming in such a way that said at least one secured tab adopts a disengaged position in which no portion of said at least one secured tab is facing the retaining surface associated with the secured tab in the disassembly direction (X+) and as a result, the retaining surface associated with the secured tab can move in the disassembly direction. the first connector and the second connector being configured to engage with one another so as to reach a mounted position in which all degrees of freedom of movement of the first connector relative to the second connector are blocked, except translations in an assembly direction (X-) and a disassembly direction (X+); the connection assembly further comprising at least one tab; the connection assembly being arranged in such a way that for each tab among said at least one tab: when the tab is secured to the first connector and the first and second connector are in the mounted position, the tab is returned to a mounted position in which a retaining portion of the tab is disposed facing a retaining surface of the second connector associated with the tab in a disassembly direction (X+); the disassembly direction being a direction in which the retaining surface moves relative to the first connector upon disconnection of the second connector from the first connector; and as a result, in the mounted position, the tab prevents the second connector from disengaging from the first connector; characterized in that the connection assembly further comprises at least one securing part capable of being placed in a mounted position in which, when said at least one tab, the first and the second connector are in the mounted position, said at least one securing part prevents at least one secured tab from being biased or from deforming in such a way that said at least one secured tab adopts a disengaged position in which no portion of said at least one secured tab is facing the retaining surface associated with the secured tab in the disassembly direction (X+) and as a result, the retaining surface associated with the secured tab can move in the disassembly direction. when the tab is secured to the first connector and the first and second connector are in the mounted position, the tab is returned to a mounted position in which a retaining portion of the tab is disposed facing a retaining surface of the second connector associated with the tab in a disassembly direction (X+); the disassembly direction being a direction in which the retaining surface moves relative to the first connector upon disconnection of the second connector from the first connector; and as a result, in the mounted position, the tab prevents the second connector from disengaging from the first connector; characterized in that the connection assembly further comprises at least one securing part capable of being placed in a mounted position in which, when said at least one tab, the first and the second connector are in the mounted position, said at least one securing part prevents at least one secured tab from being biased or from deforming in such a way that said at least one secured tab adopts a disengaged position in which no portion of said at least one secured tab is facing the retaining surface associated with the secured tab in the disassembly direction (X+) and as a result, the retaining surface associated with the secured tab can move in the disassembly direction.
