A downsized, low-cost connector which can prevent an external force applied to an electric wire from transmitting to an electrical connection portion is provided. A first current is received into a gain section of the semiconductor laser and at least one other current is received into a DBR andor phase section of the semiconductor laser. With the closing apparatus according to at least one embodiment of the invention, a locking element can have a particularly simple design: it can be guided in the actuating element. The product may be used to form a desired shaped article such as plug type inserts and liners for closed containers, or it may be formed into a film, sheet, bead or pellet. The projection may further comprise a plurality of portions or fingers extending axially distally from the proximal wall, each of the extending portions or fingers may further include a living hinge. The frame-side connected portion is adapted to be engaged with the handle-side connected portion.
