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.

A buckle assembly is formed by a male portion, a female portion and a rotor. The male portion has a base body, and at least one locking leg having a first latching element. The female portion has a base body with an interior cavity and at least one guide slot. The rotor is seated in the interior cavity and has an actuation surface, a second latching element for engagement with the first latching element, and an actuating mechanism that orients the rotor in a locked position in a resting state of the buckle assembly. The male portion is locked to the female portion by inserting the locking leg into guide slot until the first latching element engages the second latching element. The male portion is released from the female portion by pressing the actuation surface to rotate the rotor until the latching elements are disengaged from each other.

A back support device for supporting a lower back of a user may include an elastic strap, a first clasping element attached to a first end of the elastic strap, a second clasping element slidably disposed over the elastic strap and configured to releasably engage the first clasping element to form a continuous loop, and a buckle element secured to a second end of the elastic strap. The buckle element is slidably disposed on a medial portion of the elastic strap for adjusting a perimeter length of the continuous loop. The continuous loop is movable between a first position in which the continuous loop has a first perimeter length and a second position in which the continuous loop has a second perimeter length via elastic elongation. The first perimeter length is less than the second perimeter length.

Provided is a buckle locking device for the tonneau cover of pick-up trucks (II), which mainly comprises a load-bearing cross bar, a slider, a handle, a buckle block, a slide fixing block, a T-bar and an extruded aluminum frame, characterized in that: when the load-bearing cross bar and the slider is pressed by the handle of the buckle locking mechanism for buckling, it can generate a downward pulling force, which can be transmitted by the load-bearing cross bar to force the whole tonneau cover frame to generate a downward pressure, so that it can cover the truck bed tightly. Moreover, through the design of the slider mechanism, the T-bar can offer better stability and better positioning. When the buckle locking mechanism is not used, it can also be hidden inside the groove of the slider.
