1. An electrical connection device comprising:
- 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.

Abstract
Electrical connection device comprising an insulating casing which contains contacts 10 into which terminals 18, fixed to the ends of the conductors 19 to be connected, are plugged.
The casing is divided into two parts 1, 2 which include means 21, 22, 23, 24, 25, 26, 43, 44 for holding the two parts 1, 2, one fitted into the other, in a first position in which the terminals 18 are immobilized (snap-in means 27), without being plugged into the contacts 10, and in a second position in which the terminals 18 are plugged into the contacts 10 and the snap-in means 27 are locked (locking means 11).

11. An electrical connection device comprising:
-
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 adapted to engage the end part of the retention arrangement and to limit the 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 terminals so as to immobilize said contact terminals in a predetermined position, said holding arrangement in said first position of the casing parts allows insertion of the terminals into the cavities and allows extraction of the terminals from the cavities; whereby in said first position of the casing parts said terminals disengaging the contact elements and the locking arrangement disengaging the snap-in arrangement, and in said second position of the casing elements the contact terminals engage the contact elements and the locking arrangement engages the snap-in arrangement so as to lock the snap-in arrangement for retention of the contact terminals. - View Dependent Claims (12, 13, 14, 15, 16, 17)
