Second, in the second connector inserted into the connector 1, it is supposed that the front end of the second connector with a shape having large width (the right-and-left length) and small length in the depth direction contact with the enclosing wall 21bb.

Since the embed aiding part 32 is formed in a certain angle against the base 31, the embed aiding part 32 is sure to connect the upper rim 33 and the lower rim 34 by the restoring force of the embed aiding part 32 towards the releasing direction. Also, when the embed aiding part 32 is bent in the side of the base 31, the stress applied to the connecting part 31 a between the base 31 and the embed aiding part 32 is alleviated by pre-shaping the embed aiding part 32 as described above and the embed aiding part 32 is refrained from breaking off.
  • the thickness of the connecting part 31 a is formed thinner than the thickness of the base 31.
