An elastic arm (2), having a shaking prevention projection (3), is formed on one connector (1), and a recess (5) for fitting engagement with the projection (3) is formed in the other connector (4). When the two connectors (1, 4) are completely fitted together, the projection (3) is engaged in the recess (5) in such a manner that front and rear surfaces (3a, 3b) of the projection (3) are held in intimate contact with front and rear surfaces (5a, 5b) of the recess (5), respectively. These surfaces (3a, 3b, 5a, 5b) are slanting. When the projection (3) is engaged in the recess (5), elastic deformation of the arm (2) is canceled. The arm (2) extends straight along a connector fitting chamber (6), and the recess (5) is formed in an outer wall (45) of the connector (4). A lock mechanism (12, 27) for locking the two connectors to each other are provided generally in opposed relation to the arm (2). Second and third arms (31, 32) for shaking prevention purposes are provided 90° out of phase with the arm (2) in opposite directions. Preferably, the second and third arms (31, 32) are disposed flush with opposite side walls (30) of the connector (1), respectively, and each of the second and third arms has a projection (34; 35) which projects from the corresponding side wall (30).
