Abstract: A connector system is provided wherein each connector (12, 16, FIG. 2 ) has a grommet retainer (102, 120) that retains a grommet (100, 114) at the rear of the connector, and wherein when the connectors are mated they securely hold a first connector within a mounting wall. Each connector has a retainer lying rearward of a grommet and having a plurality of retainer holes (104) that pass wires that extend through the grommet, the retainer having walls which engage the grommet to retain it and assure proper orientation of the retainer so the holes of the retainer and grommet are aligned. A first connector (12) which can be inserted into a hole (30) of a mounting wall (14), has resilient tines (36, 38) that press against the hole surface and that have latch parts (56) at their front ends that form shoulders (60) that engage a face (34) of the wall.
