A connecting structure includes a connecting pin, a pin catch, a biasing member, and a holder. The connecting pin has a first portion, a second portion thicker than the first portion, and a step therebetween and connects a connecting object and a connected object (objects) by being inserted into their insertion holes. The pin catch moves in a recess in one of the objects in moving directions that are not an extending direction of the insertion holes and has a pin engagement portion that engages the step. The biasing member biases the pin catch in one of the moving directions. The holder is on the one of the objects and transitions, in response to user operation, to a first state where the holder and the biasing member holds the pin catch or a second state where the pin catch is detachable from the recess.

A wearable electronic device assembly has a strap attached to the device for attaching the device to a wearer, and a connector for securing two overlapping end regions of the strap together. The connector has first and second parts configured to be secured together with the two overlapping end regions of the strap extending between them, to secure the two end regions together. The first part has a projection arranged to extend through or adjacent to the strap. The second part has a main body having an aperture to receive the projection of the first part, and a securement part movable with respect to the main body between a released position and a securement position. The projection is retained in the aperture to secure the first part of the connector to the second part of the connector.
