1. An apparatus for electrically insulating a lateral connecting portion of a laminated multi-phase busbar comprising:
an elongated housing having a first and a second housing section made of an electrically insulating material which are pivotally connected to each other along a hinge section extending in a longitudinal direction of said housing and an opening arranged opposite to said longitudinal hinge section for receiving a connecting portion of a laminated multi-phase busbar;
wherein said first housing section comprises a plurality of first engagement structures and said second housing section comprises a plurality of second complementary engagement structures, which are adapted to engage with said first engagement means when pivoting said first and second housing section towards each other from a first assembling position to a second clamping position;
a resilient bracket having a first and a second leg and an opening arranged between said first and second leg, said first and second leg and said opening of said bracket being adapted to be positioned over the peripheral surface of said first and second housing section in said second engaging position for urging said first and second housing section towards each other.
