At least one of the groove flanks of the first part includes a plurality of contact surfaces spaced apart by a clearance surface, wherein a ridge of the second part is in contact with the contact surfaces and is out of contact with the clearance surface. The contact surfaces could be spaced apart along a length of the groove flank and/or along a height of the groove flank.
