<p>A tab-receptacle of known type comprises a pair of side walls (2) upstanding from a base (1) and having edge portions (3) in-turned towards the base (1) opposite rails (9) pushed up from material at the junction of the base (1) and the side walls (2) so that a mating tab (11) will be gripped between the opposed edge portions (3) and the rails (9). A latching tongue (4) has a lance (6) for latching engagement in an aperture (12) of a mating tab (11) and a release projection (5). Catch members (15, 16) are provided on ends of strap-like extensions (13, 14) of the respective side walls (2) at the front of the receptacle and include a clasp (18) and stop lugs (17) arranged for interengagement after a predetermined movement apart of the side walls (2) (necessary for tab insertion) to prevent further deflection apart and strain of the side walls (2) otherwise caused by a misaligned tab.</p> |
