Abstract
A plug (2) that includes a plug frame (7) is inserted into an opening of a housing (4) and is retained by a pair of spring-like detent pieces (6) extending into the opening. Projecting portions (6a) on the detent pieces engage recess portions (15) on right and left hand sides of the plug frame. A cylindrical lug (13) is slidably mounted on the plug frame and includes an opening portion (14) and inclined surfaces (17) to permit plug removal. The inclined surfaces (17) serve as cams to lift the projection portions (6a) out of the recess portions (15) when the lug is moved rearwardly. A stopper (3) is insertable into the plug frame to block such rearward sliding motion of the lug on the frame to prevent removal of the plug from the housing. The stopper may include a locking inward projection (3d) for engaging a hole (13b) bored in the lug to block rearward motion of the lug on the plug frame. Alternatively, the stopper may include outwardly projecting resilient stepped pieces (3i, 3j) that fit into the hole in the lug (13). Rearward sliding motion of the lug on the frame is enabled by pressing the pieces (3i, 3j) inwardly.
