of Figure l;
Figure 3 is a partially exploded fragmentary plan view of Flgure 1 shown partly in section; and Figure 4 is a perspective view of insulating housings of the plug connector and the socket connector.
Moulded thermoplastics latchlng members in the form of end pieces 202 are intended for assembly either to a substantially rectangular plug connector housing 204 or to a substantially 20 ~ rectangular socket connector housing 206, each of which is best seen in Figure 4, for the purpose of mounting the housing 204 or 206 in an opening 208 :
: : in a panel 210, having opposite sides 212 and 214.
The housing 204, which has been moulded from thermoplastics material, has a mating face 2L6, a wire-receiving face 218, side walls 220 and 222 and end walls 224 extending between the faces .
'1~157~7 216 and 218. A plurali~y of terminal-receiving cavities 226 extends through the housing 204 between the faces 216 and 218. Electrical terminals 228 are recei~ed and suppoxted in the cavities 226 of the housing, the terminals 228 having wire-receiving portions 230 near the face 218 and receptacles 232 for receiving pins 290 of mating terminals 289 in cavities 291 in the housing 206. The terminals 28~ have wire-receiving portions 293.
Wires 234 are electrically connected to the portions 230, being received in slots therein as shown .in Figure 3, the wires 234 extending through slots 236 in the wall 222.
A lip 238 extending across the wall 220 at the wire-receiving face 218 presents a shoulder 240 facing in the direction of the mating face 216, lips 242 provided on the wall 222, between the slots 236, presenting shoulders 244 facing in the same direction as the shoulder 240.
As seen in plan view in Figure 3, each end : . piece 202 is substantially L-shaped, having first and second arms 246 and 248, respectively, having internal surfaces 250 and 252 which meet to define a pocket to receive one side of the wire-receiving end of the housing 204. As best seen in Figure 3, a latch arm 270 has a barb 276 presenting an outwardly extending latching shoulder 278, and being formed . . .

11~5797 on the free end of a cranked shaft 274 connected at 272 to a wall 268 of an outer recess 249 in the arm 248. As best seen in Figure 1, the arm 246 has two identical flanges 258, one on each of two opposite sides of the surface 250 and being arranged in rotational symmetry, each flange 258 having an inwardly projecting lip 260 and being dimensioned to engage over one of the lips 238 and 242 of the housing 204, when the end piece 202 has been assembled thereto, so that shoulders 261 of the lips 260 bear against the shoulders 240 and 244 of the lips 238 and 242 as best seen in Figure 2. The arm 248 is divided into two portions 249', between which the latch arm 270 extends.
The portions 249' are identical, bein.g arranged in rotational symmetry, each portion 249' having an abutment face 264 from which projects a key 266. A rectangular boss 254 is provided on the : surface 250.
In order to mount the housing 204 in the opening 208 in the panel 210, an end piece 202 ~ is pushed onto each end of the terminal.receiving : end of the housing 204, as will be apparent from : Figures 1 and 3, so that the flanges 258 are cammed outwardly by engagement with the lips 238 and 242 and then snap there over, the bosses 254 being snugly received in the cavities 226 to - 5 - :
1~5797 stabilize the end pieces 202 with respect to the housing 204. The housing 204 with the end pieces 202 thereon, is then moved through the opening 208 in the panel 210 from its side 212, with the mating face 216 of the housing 204 leading, the latch arms 270 being cammed towards one another by the walls of the opening 208 until the barbs 276 thereof pass these walls.
The housing 204 is stabilized in the opening 208 by virtue of the abutment of the faces 264 against the side 212 of the panel 210 and the engagement of the keys 266 in the opening 208 (as shown in Figure 12), the shoulders 278 of the latch arms 270 bearing against the opposite side~ .
214 of the panel 210.
The socket connector housing 206 has a mating face 216', a wire-receiving face 218', side walls 220' and 222' and end walls 224'. A
recess 201' in the housing 206 is dimensioned to receive the plug housing 204, as best seen in Figure 2. The housing 206 has a latch member 292 (FLgure 2i for engaging complementary ribs `~ 286 on the wall 220 of the housing 204 as shown in Figure 2, a handle 285 being provided on the 25 side wall 220' between~slots 284 therein, for dlsengaging the member 292 from the ribs 286.

As sh~wn in Figure 2, the wire-receiving face 218' of the.housing 206 is enclosed by a cover member 288 having flanges 295 clipped over lips 238' and 242' at the wire-receiving face 218'.
An identical cover member tnot shown) may be employed to enclose the wire-receiving face 218 of the housing 204, between the end pieces 202. The cover member 288 may be made by plastics extrusion.
The end pieces 202 may be similarly assembled to the housing 206 for mounting it in a hole in a panel.
Since each end piece 202 is symmetrical about ..
a plane perpendicular to, and bisecting, the surface 252, i.e. a plane parallel to the side walls 220 and 222 and bisecting the wire-receiving and the mating faces 218 and 216, the end piece 202 can be assembled to either end of the housing 204 or 206.
