associated tab 41 through the slot 18 with an audible click the assembly motion of the second connector 19 produces a connector to connector lock sometimes referred to as 34 hand shaking 34 this condition is depicted in fig8 where it can be seen that upon full assembly of both connectors 19 in a slot 18 with their stop edges 35 abutting or close to the faces of the web 13 the strap 45 of one connector 19 is received and locked between the projections 51 52 of the other connector and vice versa this result is achieved by the pyramid configuration of the lead or front projection 51 a face 83 fig1 of each projection 51 works as a cam to deflect the advancing strap 45 of the opposite connector laterally outwardly and past this first or lead projection 51 until the strap is able to snap back into its plane and between the opposed projections 51 52 of the receiving or opposite connector a study of fig7 reveals that when contact between the rib 63 and the adjacent vertical slot edge 73 is established the connector 19 is confined laterally thus when two connectors 19 are assembled in the same slot 18 significant lateral movement is prevented and the connectors are snugly held laterally against one another and a precisely controlled module length is achieved throughout a ceiling grid this confinement assures that the straps 45 are held in the space between pairs of projections 51 and 52 for a reliable connection as discussed earlier the width of the strap 45 in.
