A connecting-device for a switchgear apparatus, includes: tulip-cluster-portions for electrically engaging with a contact-stud-element; a mounting-end-part for the mechanical connection to a pole-terminal, and conductive-transmitting-portions for transmitting electrical current from the contact-stud-element to the pole-terminal, each of the conductive-transmitting-portions extending from the respective tulip-cluster-portion to a respective base-portion of the mounting-end-part. The tulip-cluster-portions with the respective conductive-transmitting-portions and with the respective base-portions are integral with one other so as to define respective single-piece-portions.
