A cap comprises a hollow body (2) closed at the top by a plate (3) incorporating a hole, a lid (4) hinged on said body (2) and incorporating a stopper for closing said orifice. A tamper-proof device comprises snap-in elements secured to said plate and also, by a frangible connection, to said lid (4). Said device comprises two side pieces enclosing the hinged lid (4) and secured to the latter by means of frangible links (13). Sections of the edge piieces (12) and of zones (17) are provided with complementary snap-together mouldings (19, 20), the resistance of the latter to separation being greater than that of the frangible links (13). |
