Abstract
A locking mechanism is provided for securing two plastic pieces (16) and (20) together. The locking mechanism includes two longitudinal pins (10) and (12) which are secured at one end thereof in the endpiece (16). The other end is tapered and is inserted through channels (30) and (32) into the other endpiece (28). Kinked portions (18) and (20) are provided in the ends of the pins (10) and (12) to increase the effective diameter of the pins such that it is greater than the diameter of the channels (30) and (32). Strain-relief cavities (40) and (42) are provided at the ends of each of the channels (30) and (32), respectively, to receive the respective kinked portions (18) and (20).
