the first reinforcing ribs radially protrude from a hole wall of the first through hole and extend in an axial direction, and each first reinforcing rib is inserted into a gap between two adjacent elastic claws to restrict the elastic claws from moving in the circumferential direction.

13. The cable fixation device of claim 12, wherein:

the end cap includes:

an end wall having first and second sides opposite in an axial direction of the first through hole;

a cylindrical portion formed protrudingly on a surface of the first side of the end wall;

a clip connected to a peripheral portion of the end wall and extending and protruding from a second side of the end wall to snap onto the housing; and

a plurality of second reinforcing ribs connected to the end wall and an outer surface of the cylindrical portion,

the first through hole penetrates the end wall and the cylindrical portion in the axial direction, and the cylindrical portion is tapered.

14. The cable fixation device of claim 13, wherein:

a raised locating post is formed on a surface of the second side of the end wall, the locating post engaging a receptacle on the cable clamp.

15. The cable fixation device of any one of claims 11-14, further comprising:

a sealing member assembled on a side of the body portion of the cable clamp opposite to the elastic claw and formed with a second through hole allowing the cable to pass therethrough,

the seal is adapted to be inserted into a cable port on the housing for insertion of the cable to effect a seal between the cable and the housing.

16. The cable fixation device of claim 15, wherein:

the seal includes:

the second through hole penetrates through the sealing body along the axial direction; and

a connecting leg comprising an end portion and a neck portion connected between the seal body and the end portion,

the connecting leg passes through an insertion hole on the cable clamp, and the end portion abuts against the other side of the body portion of the cable clamp to assemble the sealing member to the cable clamp.

17. A connector, comprising:

a housing having a cable port for inserting a cable;

a cable inserted into the housing via the cable port; and

the cable fixation device of any one of claims 11-16, being sleeved over the cable and securing the cable to the housing.

18. The connector of claim 17, further comprising:

a terminal mounted in the housing and having a first end electrically connected to the exposed conductor of the cable and a second end adapted for mating connection with a mating terminal.

19. The connector of claim 17, wherein:

the cable clamp body portion abuts against an end face of the cable port, the cable fixing device including a seal inserted into the cable port;

the seal is radially compressed between the cable and an inner wall surface of the cable port, and both axial sides of the seal are respectively abutted between the body portion of the cable clamp and a radially positioned surface in the cable port.

20. A connector assembly, comprising:

the connector of any one of claims 17-19; and

a mating connector that mates with the connector.
