Multi-Contact Connector

A connection assembly comprising:

• a first multi-contact connector case including at least two locking zones each including a series of teeth perpendicular to a first axis, the teeth in each series being regularly spaced apart, the two locking zones being separated from each other by a gap including a first height measured along said first axis;
• and
• a second multi-contact connector case configured to be assembled with the first case, the second case comprising a case body and a locking cap movable relative to the case body perpendicular to said first axis between an unlocked position and a locked position, the locking cap including at least two elastically deformable tabs, each provided with a locking zone including a series of teeth perpendicular to the first axis, the teeth in each series being regularly spaced apart, each locking zone of one of the elastically deformable tabs co-operating with one of the locking zones of the first case when the two cases are assembled together and the locking cap is in the locked position, the locking zones of the second case being separated from each other by a gap having a second height measured along said first axis, the second height being different from the first height;
• the series of teeth in the locking zones of both cases all including a same pitch, and a difference between the first and second heights not being equal to a multiple of the pitch of the series of teeth.
