In the housing (2) there is at least one hole (3) of wire input leading towards the appropriate clip point and an actuating channel (14) located near the hole (3) for insertion of the actuating tool (13) and opening of the respective clamping spring (6). The channel (14) ends in the actuating portion (12) of the clamping spring (6) adjacent across the longitudinal direction (L) towards the clip point for the electric wire (15). The clip point and the actuating portion (12) lie next to each other along the width of the clamping spring (6). Holes (3) that are set by main axes for wire insertion and the actuating channel (14) and crossing across the longitudinal direction of the clamping spring (6) in the zone of the clip point through the width of the clamping spring (6) of the plane are approximately parallel to each other. |
