In order to reliably lock an electric plug and socket assembly (1) including an outer part (2) and inner part (3) which can be coupled to the outer part, the inner part is provided with a recess (17,17') into which, when the two parts are coupled, a snap-on hook means (14,14') is engaged and maintained so as to act as a spring. When the plug and socket assembly (1) is in a locked position, the snap-on hook means (14) or each snap-on hook means is locked against radial excursion since it rests on a bushing (7) which is axially displaceable on the outer part (2). In the locked position, the backward pulled bush (7) releases the snap-on hook means (14,14') thereby allowing for disengagement of the outer and inner parts (2,3). In order to enable the plugging of the parts (2,3) when the bushing (7) is in the locked position, the snap-on hook means (14') is provided with two spring legs (14c) whose end cam (14'a) and an inner contour (41) running into the recess (17') of the inner part (3) form a guide for the two leg snap-on hook means (14'). |
