A fastening system for fastening a distribution member, such as a pump, on a neck of a reservoir to form a distributor for a fluid product includes a fastening ring and a rigid collar, the ring including a skirt intended to be engaged around the neck. The skirt includes articulated fastening tabs angled outwards with respect to a central axis X of the ring, and the collar is able to be moved with respect to the skirt and engaged around the skirt so as to fold back the articulated tabs to a radial alignment with the axis X. The ring with the collar is then able to be assembled on the neck and able to be disassembled from the neck without relative movement between the ring and the collar, and the articulated tabs have an internal fastening means that can engage with an external fastening means of the neck

A pipe connector having a body with a tubular part to seal with a pipe. The tubular part has an outer face with a projecting feature to seal with the pipe. A collet is fixed to the body and spaced from the tubular part to form a cavity for the pipe. A locking cap is captive on and screwed onto collet to deflect the collet onto the pipe and the pipe onto the tubular part to seal between the body and the pipe. The collet has through slots at its distal end allowing the pipe to be visible when the connector is locked and unlocked. The inner diameter at an open end of the collet is optionally greater than the inner diameter of the distal part that receives the pipe. A method of forming the connector is also disclosed.

A method produces an elastically deformable molded part having a number of undercut molded-part regions, by use of a mold. To provide a technique which makes it possible to produce individual molded parts which are elastically deformable and have undercut regions from soft materials in a precise and cost-effective manner, a method is performed in which a molded-part material is introduced into the mold. The mold has a shaping contour with a number of special contour regions, which are configured for shaping the number of undercut molded-part regions of the molded part, and in which the molded part is removed from the mold by at least partially deforming the mold together with the molded part therein in such a way that the molded part elastically deforms and the mold at least partially, but in any event to the extent of the special contour regions, breaks up.

A method for integrally forming a sole with hobnails includes the following steps: providing a mold assembly, the mold assembly includes a sole forming member and a hobnail forming member, the hobnail forming member is movable with respect to the sole forming member; forming of sole and hobnails, injecting plastic material into the mold cavity to integrally form the sole and a hobnail; demolding the hobnail, moving the hobnail forming member with respect to the sole forming member to create a buffer space between the hobnail and the hobnail forming member; and demolding of the sole, taking the sole with the hobnail obtained by the previous step out of the mold assembly, wherein an arc-shaped paw portion of the hobnail is bent through the buffer space and then demolded.
