A connector housing (10) is formed with a mount hole (21) for a retainer (60), and the retainer (60) is inserted into the mount hole (21) to lock and retain terminal fittings (40) inserted into cavities (13). Partition walls (28) partitioning the cavities (13) adjacent in width direction in the connector housing (10) are provided with extended walls (28) projecting into the mount hole (21). The retainer (60) is provided with recesses (66) at positions corresponding to the extended walls (28). A creepage distance between the terminal fittings (40) adjacent with the partition wall (27) therebetween is made longer by the extended wall (28), whereby the short circuit of the adjacent terminal fittings (40) can be prevented.

What is claimed is: 1. A connector, comprising: a housing formed with opposite front and rear ends and opposite first and second outer surfaces extending between the ends, a plurality of substantially adjacent cavities arranged substantially side by side in a width direction between the first and second outer surfaces, each cavity having opposite first and second inner surfaces aligned substantially in the width direction, partition walls formed between the adjacent cavities and extending from the first inner surface to the second inner surface of the respective cavities for partitioning the adjacent cavities, at least one mount hole formed in the housing and extending from the first outer surface to the first inner surface for communicating with the cavities, extended walls extending from the respective partition walls and projecting into the mount hole farther than all positions on the first inner surfaces of the cavities adjacent to the mount hole; and at least one retainer mountable into the mount hole of the housing, locking sections provided on the retainer and disposed for projecting into the respective cavities, the retainer being formed with recesses engageable respectively with the extended walls when the retainer is inserted to a proper depth in the mount hole. 2. The connector of claim 1, wherein the mount hole has an outer opening in the first outer surface of the housing and inner openings in the first inner surfaces of the respective cavities, the retainer being inserted into the mount hole from the outer opening towards the inner openings to insert the locking sections thereon into the cavities through the inner openings. 3. The connector of claim 2, wherein projecting ends of the extended walls are closer to the outer opening than to the inner openings. 4. The connector of claim 1, wherein the retainer is movably positioned in the housing between a first position where the locking sections are substantially retracted from the cavities and a second position where the locking sections are in the cavities. 5. The connector of claim 4, wherein opening ends of the recesses are engaged partly with the projecting ends of the extended walls when the retainer is at the first position. 6. The connector of claim 1, wherein each of the extended walls is a plate extending substantially in a mounting direction of the retainer into the mount hole and has a thickness narrower than the partition wall. 7. The connector of claim 6, wherein the extended wall extends over substantially the entire length of the mount hole in forward and backward directions with a substantially uniform width. 8. A connector, comprising: a housing with opposite front and rear ends and opposite first and second outer surfaces extending between the ends, a plurality of substantially adjacent cavities arranged substantially side by side in a width direction between the first and second outer surfaces, each cavity having opposite first and second inner surfaces aligned substantially in the width directions, partition walls formed between the adjacent cavities and extending from the first inner surface to the second inner surface of the respective cavities for partitioning the adjacent cavities, at least one mount hole formed in the housing and extending from the first outer surface to the first inner surfaces for communicating with the cavities, extended walls extending from the respective partition walls and projecting into the mount hole farther than all positions on the first inner surfaces of the cavities adjacent to the mount hole; terminal fittings disposed respectively in the cavities; and at least one retainer mountable into the mount hole of the housing, locking sections provided on the retainer and disposed for projecting into the respective cavities for locking the terminal fittings in the cavities, the retainer being formed with recesses engageable respectively with the extended walls when the retainer is inserted to a proper depth in the mount hole. 9. The connector of claim 8, wherein projecting ends of the extended walls are closer to the outer opening than to the inner openings. 10. The connector of claim 8, wherein the mount hole has an outer opening in the first outer surface of the housing and inner openings in the first inner surfaces of the respective cavities, the retainer being inserted into the mount hole from the outer opening towards the inner openings to insert the locking sections thereon into the cavities through the inner openings, whereby the locking sections lock and retain the terminal fittings inserted in the cavities. 11. The connector of claim 10, wherein the locking sections are configured to enter the cavities through the mount hole and further enter constriction spaces adjacent to constricted portions of the terminal fittings, whereby the locking sections and portions of the terminal fitting are substantially opposed to each other in a detaching direction. 12. The connector of claim 8, wherein the retainer is movably positioned in the housing between a first position where the locking sections are substantially retracted from the cavities to permit the insertion and withdrawal of the terminal fittings into and from the cavities and a second position where the locking sections are in the cavities, thereby causing the locking sections to act on the terminal fittings that have been inserted properly into the cavities. 13. The connector of claim 12, wherein opening ends of the recesses are engaged partly with the projecting ends of the extended walls when the retainer is at the first position. 14. The connector of claim 8, wherein engaging portions project from side walls of the terminal fittings substantially facing the mount hole and the terminal fittings are retained by the engagement of the locking sections with the engaging portions. 15. The connector of claim 14, wherein the engaging portions are distanced from the adjacent partition walls and are substantially in widthwise centers of the side walls. 16. The connector of claim 8, wherein each of the extended walls is a plate extending substantially in a mounting direction of the retainer into the mount hole and has a thickness narrower than the partition wall. 17. The connector of claim 16, wherein the extended wall extends over substantially the entire length of the mount hole in forward and backward directions with a substantially uniform width. 18. A connector, comprising: a housing formed with opposite front and rear ends and opposite first and second outer surfaces extending between the ends, a plurality of substantially adjacent cavities arranged substantially side by side in a width direction between the first and second outer surfaces, each cavity having opposite first and second inner surfaces aligned substantially in the width direction, partition walls formed between the adjacent cavities and extending from the first inner surface to the second inner surface of the respective cavities for partitioning the adjacent cavities, at least one mount hole formed in the housing and extending from the first outer surface to the first inner surface for communicating with the cavities, extended walls extending from the respective partition walls and projecting into the mount hole to positions closer to the first outer surface of the housing than to all positions on the first inner surfaces of the cavities adjacent to the mount hole, each extended wall extending over substantially an entire length of the mount hole in forward and backward directions and having substantially uniform widths that are narrower than the respective partition wall; and at least one retainer mountable into the mount hole of the housing, locking sections provided on the retainer and disposed for projecting into the respective cavities, the retainer being formed with recesses engageable respectively with the extended walls when the retainer is inserted to a proper depth in the mount hole.
