  • an insulating casing consisting of first and second casing parts, said first casing part formed with a plurality of cavities, each said cavity adapted to receive a terminal having a retention arrangement formed with a retention collar extending outwardly from a body of the terminal and an end part, said second casing part having a plurality of contact elements and a locking arrangement, said first and second casing parts being movable with respect to one another and along axes of the cavities between first and second positions;

    a snap-in arrangement situated at each said cavity of the first casing part, said snap-in arrangement in each said cavity containing a stop portion and a holding arrangement, said stop portion being adapted to engage the end part of the retention arrangement and to limit a depth of insertion of the terminals into the respective cavities;

    said holding arrangement being adapted to engage opposite sides of the retention collar and to hold the terminals in a position inserted into said cavities;

    in said first position of the casing parts said snap-in arrangement engages the collar of the terminal so as to immobilize said contact terminals in a predetermined position, in said first position the terminals are disconnected from the contact elements and the locking arrangement disengages the snap-in arrangement; and

    in said second position the contact terminals being connected to the contact elements and the locking arrangement engages the snap-in arrangement for retention of the contact terminals.
