A buckling device used in conjunction with a strap for holding an object firmly in position is provided. The buckling device includes a male fastener and a female fastener. The male fastener includes a strap-mounting body for fixing a first end of the strap thereto and a tongue-like member formed on the strap-mounting body. The female fastener includes a rectangular body having a hollowed inside and formed with an insertion hole; a locking/releasing piece pivotally mounted on the rectangular body; and an elastic piece provided at the insertion hole. To engage, the tongue-like member on the male fastener is inserted into the insertion hole in the female fastener. The tongue-like member pressed on the elastic piece such that the elastic piece is bent downwards and thereby urges forcibly against the tongue-like member, thereby locking the tongue-like member in position in the female fastener and thus securely engages the male fastener with the female fastener. To disengage, the user can simply pull up the locking/releasing piece so that it is pivotally erected about the pivoting pins, thereby causing the tongue-like member to be ejected away from the locking position and out of the female fastener. The engagement and disengagement can be both carried out by the user quickly in just one step of operation.
Swim goggles comprising first and second substantially rigid frames each having a base portion, an eye lens portion, an inner end portion and an outer end portion. The swim goggles further comprise a bridge for engaging the inner end portions of the first and second frames. The swim goggles further comprise a head strap having first and second end portions having a plurality of tooth portions. The swim goggles further comprise first and second connection mechanisms disposed at the outer end portions of the first and second frames, respectively. Each of the first and second connection mechanisms comprise a strap passage way adapted to receive the first and second end portions of the head strap, respectively. Each of the first and second mechanisms further comprise a unitary resilient pawl comprising a median portion and first and second finger portions having end portions engaged with the base portion at a position adjacent to and below the eye lens portion. The resilient pawl further comprising a button portion extending upwardly from the median portion and a stop portion extending downwardly from the median portion. Each of the first and second connection mechanisms further comprise a cover portion engaged with the base portion and the end portions of said first and second finger portions, respectively. The cover portion has an annular shaped opening adapted to receive the button portion. In operation, movement of the button portion by the person causes the first and second finger portions to become biased and the stop member to become disengaged from the tooth portion of the strap. Release of the button portion causes the stop member to return to its unbiased state and engaged with the tooth portion of the strap.
