Abstract
According to the invention, there is provided a coupler which is realized in the form of an integral unit made of an elastic synthetic resin material which is free from any risk of losing any of its components and can be temporarily but securely held in aligned bores of the plaques it is going to couple once it is introduced into the bores so that the plug body of the coupler may be pushed into the socket body with ease. Moreover, since the socket body of the coupler firmly held in the bores of the plaques to be coupled and the plug body pushed into said socket body are connected with each other by means of a pair of thin support members to form an integral coupler unit, said plug body can be pushed into said socket body with a relatively small force to securely rigidly couple the plaques. As there are no parts of the unit which are prone to damage, it is good for repeated use.
