Male and female housings (10, 20) are connected and locked together by the engagement of a lock arm (22) of the female housing (20) and a lock (18) of a receptacle (12). Upon separating the two housings (10, 20), an operable portion ( 24) at the rear end of the lock arm (22) is operated to disengag

Male and female housings (10, 20) are connected and locked together by the engagement of a lock arm (22) of the female housing (20) and a lock (18) of a receptacle (12). Upon separating the two housings (10, 20), an operable portion ( 24) at the rear end of the lock arm (22) is operated to disengage the lock arm (22) from the lock (18), thereby canceling the locked state. Since the operable portion (24) is located in a notch (17) formed at the front end edge of the receptacle (12) with the two housings (10, 20) connected, a connector can be miniaturized with respect to a connecting direction of the two housings (10, 20).

What is claimed is: 1. A connector, comprising: a first housing with a receptacle having an open front end, a lock formed in the receptacle; and a second housing fittable into the receptacle for connection with the first housing, a lock arm cantilevered rearwardly on the second housing and being engageable with the lock in the receptacle to lock the housings together, an operable portion being formed on a rear end of the lock arm and being operable to cancel a locked state of the housings so that the housings can be separated, wherein: a notch is formed at a front edge of the receptacle, the operable portion is at least partly in the notch and exposed outside of the receptacle when the housings are connected, and two finger placing portions disposed respectively at opposite sides of the operable portion and substantially adjacent a rear end of the second housing, the finger placing portions being completely in the notch when the housings are connected, each of said finger placing portions including a standing wall projecting from the second housing and a finger touching plate extending towards the operable portion from an outer end of the standing wall. 2. The connector of claim 1, wherein a rear end of the second housing is flush with or internally of a front end of the receptacle when the housings are connected. 3. The connector of claim 1, wherein the finger placing portions project out beyond an outer surface of the receptacle. 4. The connector of claim 1, wherein an outer surface of the operable portion projects more outward than an outer surface of the receptacle. 5. The connector of claim 1, wherein a guiding recess is formed at a rear edge of the notch. 6. The connector of claim 1, wherein the lock arm comprises a guiding surface for guiding a resilient deformation of the lock arm. 7. A connector, comprising: a first housing with opposite front and rear ends, a forwardly-open receptacle extending into the front end, a notch extending rearwardly into the open front end of the housing, and a lock projecting into the receptacle from a location on the housing adjacent to and rearward of the notch; and a second housing having opposite front and rear ends and being fittable into the receptacle for connection with the first housing, the second housing being dimensioned so that the rear end of the second housing is flush with or forward of the front end of the first housing when the housings are connected, a resiliently deflectable lock arm cantilevered rearwardly on the second housing and having an engaging portion engageable with the lock in the receptacle to lock the housings together, an operable portion in proximity to a rear end of the lock arm and being operable to deflect the lock arm for canceling a locked state of the housings and at least one finger placing portion projecting substantially rigidly from the second housing substantially adjacent the lock arm, the operable portion and the finger placing portion being in the notch when the housings are connected, whereby the finger placing portion is engageable when the lock arm is deflected so that the housings can be separated. 8. The connector of claim 7, wherein two finger placing portions are located at substantially opposite sides of the operable portion of the lock arm. 9. The connector of claim 8, wherein the finger placing portions project out beyond an outer surface of the receptacle. 10. The connector of claim 7, wherein an outer surface of the operable portion projects more outward than an outer surface of the receptacle. 11. The connector of claim 7, wherein the second housing further comprises first and second standing walls substantially adjacent the rear end of the second housing and projecting from opposite respective sides of the lock arm and first and second finger touching plates extending towards one another and partly over the lock arm from projecting ends of the first and second standing walls respectively, the operable portion of the lock arm being between the finger touching plates.
